feat(meshopt): add typed enums and improve naming logic

Introduce SimplifyOptions and SimplifyVertexOptions enums for mesh simplification, replacing magic numbers with type-safe flags. Update MeshOptApi with strongly-typed wrapper methods. Refactor MeshletUtility to use new enums and nullable delegates, and fix stride calculation for pointer arithmetic.

Rename NamingConventions.GetMethodName to GetName, update name removal logic to use "$TBare", and add ALL_CAPS style for constants. Update config files to match new naming conventions and add ALL_CAPS constant rule for meshopt. Refactor BindingParser and related classes to support constant member kind. Apply minor bug fixes and code style improvements throughout.
