feat: Add clip-path support for iOS

[paradowstack]

Summary:

This PR adds support for clip-path CSS attribute for JS. It follows CSS spec described here. It does not provide support for SVG source (<clip-source> values), what can be added in the additional PR if needed. Supported syntax is [<basic-shape>] || <geometry-box>] with almost full support of every basic shape (<basic-shape> = circle | ellipse | rect | polygon | inset | xywh) and references boxes (<geometry-box> = margin-box | border-box | padding-box | content-box | fill-box | stoke-box | view-box).

Work has been split into three PRs for more convenient reviewing process. This part adds iOS support for clipping, path and bounds calculations, native CSS parser.

Changelog:

[IOS] [ADDED] - Add clip-path support for iOS

Test Plan:

Merge JS and Android PRs and run RNTester app.

• Test Clip Path screen in RNTester app (ClipPathExample.js)
• C++ CSS parser tests (CSSClipPathTest.cpp)
