Electra: (partial) spectests

[prestonvanloon]

What type of PR is this?

Other

What does this PR do? Why is it needed?

This PR includes:

• All buildable spectests
  • Some spectests are not included because the electra functions have not landed in develop yet
• Re-exports of functions from prior forks (i.e. things that didn't change in electra)

Which issues(s) does this PR fix?

Tracking @ #13849

Other notes for review

I want to introduce this technique of re-exporting methods that haven't changed in the current fork.
When you look at deneb spectests, I found it very strange to see spectests testing
altair.ImportantFunction instead of deneb.ImportantFunction. I was asking myself if this was a
mistake or intentional. With this re-export pattern, electra will export altair.ImportantFunction
and that will be clear to the reader that we are testing electra.ImportantFunction for spec
compliance, but the internals are not changed since altair via the re-export.

Draft until #13976 merges.

Currently missing spectests for electra:
