Subject: Add half-precision matrix type aliases in GLSL (#7066)

Fixes #6708

This commit adds type aliases for half-precision matrices, including
f16mat3x2, f16mat3x3, f16mat3x4, f16mat4x2, f16mat4x3, and f16mat4x4.
Convenience aliases for square matrices (f16mat2, f16mat3, f16mat4) are
also added.

This commit introduces a new test file that validates the usage of
half-precision types in a compute shader context.
