Adding cultureName to GeneratedRegexAttribute

[joperezr]

Fixes #59492

This adds changes the default behavior of the source generated engine to use Invariant Culture for case-sensitive comparisons, as well as adds two APIs on the GeneratedRegex attribute that take in a cultureName that let's the user override that behavior. This also updates the regex source generator's analyzer and codefixer to be explicit into which constructor it picks and select the one that has the explicit cultureName with it.

Note: This API hasn't been approved yet, hence I'm starting the PR as a draft, and we will take this API to review next Tuesday.

Looks great, thanks.

The wasm failure is unrelated to this PR, so I'll go ahead and merge.
