Vulkan: Fix matrix uniforms A piece of code shared with d3d was used to implement this feature. However, we store the uniform data transposed and row-major in d3d to accomodate the fact that matrix indexing in HLSL is the opposite of GLSL (mat[row][col] in HLSL as opposed to mat[col][row] in GLSL). There were two functions that copied the source matrix fields either as column-major or source-major (corresponding to `transpose` false or true respectively in glUniformMatrix*) into a row-major destination. These functions are refactored into one, which copies from any-major source to any-major destination. The HLSL backend uses the "to row-major" variant and the Vulkan backend uses the "to column-major" variant.
