[vector_math] Document geometry filter APIs

[faheemabbas766]

Documents the public geometry filter APIs in vector_math.

This removes public_member_api_docs ignores from geometry filter implementations by adding doc comments for the public filter classes, constructors, properties, and methods.

Part of flutter/flutter#186827.

Code Review

This pull request removes public API documentation ignore rules and adds doc comments to various geometry filter classes in vector_math_geometry. Feedback suggests clarifying the documentation regarding in-place mesh mutation for inplace and InplaceGeometryFilter, and optimizing the requires and generates getters in GeometryFilter by returning const empty lists to avoid unnecessary allocations.

Code Review

This pull request removes the public member API documentation ignore rules and adds documentation comments to several geometry filter classes, including BarycentricFilter, ColorFilter, FlatShadeFilter, GeometryFilter, InplaceGeometryFilter, InvertFilter, and TransformFilter. Additionally, the requires and generates getters in GeometryFilter are updated to return constant empty lists. There are no review comments, so no feedback is provided.

Following the source-repo guidance from #12, I’ve submitted these vector_math documentation changes upstream here: google/vector_math.dart#373

This upstream PR includes the geometry filter docs from this PR as well as the related Plane API docs.
