Add enableIOSCompressedTextFrameAdjustment feature flag (#57407)

Summary:

Add the generated React Native feature flag plumbing for `enableIOSCompressedTextFrameAdjustment`. The flag gates an iOS `Text` rendering adjustment that expands and recenters compressed explicit `lineHeight` drawing when font glyph bounds exceed the drawing frame.

Changelog:
[iOS][Added] - Add `enableIOSCompressedTextFrameAdjustment` feature flag for `Text` rendering adjustments.

Differential Revision: D110430299
