Added Debug_Editor/Release_Editor configs to all projects and solution. Refactored test utilities into Ghost.TestCore and updated references. Introduced DXCBindingTest for shader compilation. Updated conditional compilation to use GHOST_EDITOR. Improved platform mappings and performed minor code cleanup.
Replaces all Misaki.HighPerformance.Mathematics vector, quaternion, and matrix types in Ghost.Ufbx bindings with new native ufbx_vec2, ufbx_vec3, ufbx_vec4, ufbx_quat, and ufbx_matrix structs. Updates all interop code, struct fields, and API signatures accordingly. Adds struct definitions for the new types and provides matrix operations as struct methods. Removes unnecessary math package reference. Also includes minor fixes to system attributes, meshlet LOD logic, and mesh utility.
BREAKING CHANGE: All Ufbx-related APIs now use ufbx_* types instead of Misaki.HighPerformance.Mathematics types. Existing code using the old types will require updates.
