[browser][non-icu] HybridGlobalization compare

[ilonatommy]

Implements a chunk of web-api based globalization. Is a part of HybridGlobalization feature and contributes to #79989.

Old, icu-based private API: GlobalizationNative_CompareString

New, non-icu private API: CompareString.

Affected public API (see: tests in CompareInfoTests.Compare.cs):

• CompareInfo.Compare,
• String.Compare,
• String.Equals.

All changes in behavior are listed in docs\design\features\hybrid-globalization.md

Test name	time ICU4C [ms]	time HG [ms]	increase by [times]
String, String Compare	0.0448	5.029	112
String, String Equals	0.0450	4.9587	110
String, CompareInfo Compare	0.0451	4.9238	109

see final performance here: #85098

Performance:
most of the processing time is taken by mono_wasm_compare_string (~60-70%) while ~50% is used for TextDecoder.decode and only up to 20% for localeCompare.

Failures: Blazor WasmBuildTests and AOT timeouts are not connected.

[kg]

In the future, could we use attributes or a compile time analyzer to make builds fail when the user's code attempts to use these combinations? (Obviously not in this PR)

[ilonatommy]

I think we could but I am not sure if I know how to do it. Do we have a similar mechanism somewhere already?

[kg]

I'm not sure, maybe ask in the group chat or channel. I haven't touched any of our generators/analyzers but I know we have a couple like the JSImport/Export generator.

Failures not related. Merging to move forward. If there are any new ideas later, feel free to let me know and we will solve them in a follow-up, cc @pavelsavara, @radical.
