[browser] Limit PNSE in `HybridGlobalization`

[ilonatommy]

#95920 updated the doc with APIs that are throwing PlatformNotSupportedException by design. Consider:

• implementing invariant SortKey in HybridGlobalization
• changing comparison options to supported ones.

SortKey:

• JS does not expose API that would give us similar information to SortKey
• Intl.Collator-based implementation of SortKey could be an alternative to the original, locale-sensitive SortKey. However, we have no guarantee that the implementation would give similar results and would not cost us too much space.
• Invariant SortKey does not cover fully the original, locale-sensitive functionality, however it is the best alternative when it comes to saving space - it's already implemented, we would reuse existing code. Document the changes in behavior.

CompareOptions:

• some combinations of compare options are not supported (see the doc)
• APIs in other, non-globalization libs use these combinations, becoming not supported
• Check if they would not work equally good with another compare options set that is supported and document the changes in behavior.

Old issue discussing the possibilities:
#84621
