Should be faster in most practical cases, though can be slower if an inserted edge must cross a lot of existing edges.

Benchmark configuration:
- Test scene with 4 meshes: a mossy stone nanite mesh, a beach ball, a ball with an emissive blue cross and a hut mesh
- Target mesh: 11.8k triangles mesh, created by voxel wrapping the meshes in the test scene elements
- 4096x4096 output texture with 16x multisampling baking BaseColor, Emissive, PackedMRS and Normal maps
- 4096x4096 photo capture resolution
Unreal Insights reports the following times for the Bake call:
- Before this change: 2 mins 45 seconds
- After this change: 55.9 seconds
Aside: (Unaffected by this change) In both cases the photo capture, which is done on the game thread, took about 1 min

- Constrained edges along a boundary are allowed to collapse, and vertices are allowed to move, but they are projected back to the original boundary curve geometry
- Additionally, vertices at boundary "corners" (defined using an angle threshold criterion) are constrained to not move or be deleted

Deprecation of FPlatformMath::IsNegative*() functions.
New FPlatformMath::IsNegativeOrNegativeZero().
Fix up of existing usage to either use < 0 or IsNegativeOrNegativeZero where appropriate.
Fixes for aliasing problems in various FMath functions, including IsNegative*().
Resubmission of CL# 19833778 with fixes for problematic Mac and Android toolchains, causing spurious errors while building PCHs.
