Metal: Fix crash when compiling compositor shaders.

Although viewport compositor isn't supported yet on Apple deviced the
shaderlibs are compiled. The compositor shaders uses mat3 constructor
with a single vec3 and 6 floats. This constructor wasn't defined in
metal so it failed the compilation.

This patch adds the override to mat3.
