Resolve URIs with special characters correctly

[mofux]

Previously, model URIs were synced with typescript without encoding (uri.toString(true)), breaking resolution of URIs that had special characters in them, e.g. file:///node_modules/@some/module or file:///C:/test.js. This fix makes sure that typescript sees the correct, encoded file URIs. I've also verified that features like Peek Definition is still working with this fix.

Fixes #3281
Fixes #3236

History:

675844a tried to introduce a fix for this problem, but only provided half the solution. This new patch still solves #2295 which was the original target for that commit, while also fixing the encoding problems entirely.

Bumping this PR as it will fix a bunch of uncaught errors that show up in console while inspecting the TypeScript playground downstream.

Any project using @typescript/ata with monaco-editor will see this issue.

Here's a TypeScript Playground repro link: https://www.typescriptlang.org/play?#code/JYWwDg9gTgLgBAbzgVwM4FMDKMCGN1wC+cAZlBCHAERTo4DGMVA3ALABQH9EAdqvAG1uyHjAC6cALwoM2POgAUABgCUbTu2Gj1QA

Inspect the page and you will see the following error:

Uncaught (in promise) Error: Could not find source file: 'file:///file%3A///node_modules/react/package.json'.

I cloned TypeScript playground locally, patched monaco-editor (particularly this change) and the error went away.
