This PR targets the #2515 PR. It does that for the sake of diffing. When this PR and #2515 are both ready, I'll merge #2515 first, then change the target of this branch, and merge this one.

Summary of the Pull Request

This PR adds support for "dynamic profiles", in accordance with the Cascading Settings Spec. Currently, we have three types of default profiles that fit the category of dynamic profile generators. These are profiles that we want to create on behalf of the user, but require runtime information to be able to create correctly. Because they require runtime information, we can't ship a static version of these profiles as a part of defaults.json. These three profile generators are:

  • The Powershell Core generator
  • The WSL Distro generator
  • The Azure Cloud Shell generator

PR Checklist

Detailed Description of the Pull Request / Additional comments

We want to be able to enable the user to edit dynamic profiles that are generated from DPGs. When dynamic profiles are added, we'll add entries for them to the user's profiles.json. We do this without re-serializing the settings. Instead, we insert a partial serialization for the profile into the user's settings.

Remaining TODOs:

Validation Steps Performed

  * Moves tests into individual classes
  * adds support for layering a colorscheme on top of another
  must have committed without staging this change, uh oh. Not like those tests actually work so nbd
  * add support to unbind a key with `null` or `"unbound"` or `"garbage"`
  In the end, I think we need to ask _was this worth it_
  Add a MsBuild target to auto-generate a header with the defaults.json as a
  string in the file. That way, we can _always_ load the defaults. Literally impossible to not.

Here we're verifying that all of the GUIDs are unique right? Why not loop through every possible combination to ensure that? (or, better yet, push all of the guids into a set and check if the GUID actually got inserted)

This PR represents the start of the work on Cascading User + default settings, #754.

Cascading settings will be done in two parts: 
* [ ] Layered Default+User settings (this PR)
* [ ] Dynamic Profile Generation (#2603).

Until _both_ are done, _neither are going in. The dynamic profiles PR will target this PR when it's ready, but will go in as a separate commit into master.

This PR covers adding one primary feature: the settings are now in two separate files:
* a static `defaults.json` that ships with the package (the "default settings")
* a `profiles.json` with the user's customizations (the "user settings)

User settings are _layered_ upon the settings in the defaults settings.

## References

Other things that might be related here:
* #1378 - This seems like it's definitely fixed. The default keybindings are _much_ cleaner, and without the save-on-load behavior, the user's keybindings will be left in a good state 
* #1398 - This might have honestly been solved by #2475 

## PR Checklist
* [x] Closes #754
* [x] Closes #1378 
* [x] Closes #2566
* [x] I work here
* [x] Tests added/passed
* [x] Requires documentation to be updated - it **ABSOLUTELY DOES**


## Detailed Description of the Pull Request / Additional comments

1. We start by taking all of the `FromJson` functions in Profile, ColorScheme, Globals, etc, and converting them to `LayerJson` methods. These are effectively the same, with the change that instead of building a new object, they are simply layering the values on top of `this` object. 
2. Next, we add tests for layering properties like that.
3. Now, we add a `defaults.json` to the package. This is the file the users can refer to as our default settings.
4. We then take that `defaults.json` and stamp it into an auto generated `.h` file, so we can use it's data without having to worry about reading it from disk.
5. We then change the `LoadAll` function in `CascadiaSettings`. Now, the function does two loads - one from the defaults, and then a second load from the `profiles.json` file, layering the settings from each source upon the previous values.
6. If the `profiles.json` file doesn't exist, we'll create it from a hardcoded `userDefaults.json`, which is stamped in similar to how `defaults.json` is.
7. We also add support for _unbinding_ keybindings that might exist in the `defaults.json`, but the user doesn't want to be bound to anything.
8. We add support for _hiding_ a profile, which is useful if a user doesn't want one of the default profiles to appear in the list of profiles.

## TODO:
* [x] Still need to make Alt+Click work on the settings button
* [x] Need to write some user documentation on how the new settings model works
* [x] Fix the pair of tests I broke (re: Duplicate profiles)


<hr>

* Create profiles by layering them

* Update test to layer multiple times on the same profile

* Add support for layering an array of profiles, but break a couple tests

* Add a defaults.json to the package

* Layer colorschemes

  * Moves tests into individual classes
  * adds support for layering a colorscheme on top of another

* Layer an array of color schemes

* oh no, this was missed with #2481

  must have committed without staging this change, uh oh. Not like those tests actually work so nbd

* Layer keybindings

* Read settings from defaults.json + profiles.json, layer appropriately

  This is like 80% of #754. Needs tests.

* Add tests for keybindings

  * add support to unbind a key with `null` or `"unbound"` or `"garbage"`

* Layer or clear optional properties

* Add a helper to get an optional variable for a bunch of different types

  In the end, I think we need to ask _was this worth it_

* Do this with the stretch mode too

* Add back in the GUID check for profiles

* Add some tests for global settings layering

* M A D  W I T H  P O W E R

  Add a MsBuild target to auto-generate a header with the defaults.json as a
  string in the file. That way, we can _always_ load the defaults. Literally impossible to not.

* When the user's profile.json doesn't exist, create it from a template

* Re-order profiles to match the order set in the user's profiles.json

* Add tests for re-ordering profiles to match user ordering

* Add support for hiding profiles using `"hidden": true`

* Use the hardcoded defaults.json for the exception->"use defaults" case

* Somehow I messed up the git submodules?

## Summary of the Pull Request

_This is attempt 2 at this feature_. The original PR can be found at #3369. 

These are settings that apply to _every_ profile, before user customizations. 

If the user wants to add "default profile settings", they can make the `"profiles"` property an _object_, instead of a list, and add `"defaults"` key underneath that object. The users list of profiles should then be under the `list` property of the `profiles` object.

## PR Checklist
* [x] Closes #2325
* [x] I work here
* [x] Tests added/passed
* [x] schema, docs updated

## Detailed Description of the Pull Request / Additional comments
~~Discussion in #2325 itself serves as the "spec" for this task. I thought we'd need more discussion on the topic, but it ended up being pretty straightforward.~~

I should not have said that in the original PR. We've had a better spec review now that I think we're happier with.
