[browser][non-icu] HybridGlobalization normalization.

[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_IsNormalized, GlobalizationNative_NormalizeString

New, non-icu private API: Interop.JsGlobalization.IsNormalized, Interop.JsGlobalization.NormalizeString

Affected public API (see: tests in Normalization\NormalizationAll.cs, Normalization\StringNormalizationTests.cs):

• String.Normalize
• String.IsNormalized

Test name	time ICU4C [ms]	time HG [ms]	increase by [times]
String, Normalize	0.7154	1.4417	2,01
String, Normalize ASCII	0.0389	0.0389	1,00
String, IsNormalized	0.2218	0.6704	3,02

WebApi is used only for unicode codes, that's why Normalize ASCII time is identical for both modes.
No changes in behavior. Hybrid Globalization JS code got split to smaller files.
