Vulkan: Clean up RGB8-to-RGBA8 ubyte function Some platforms encounter issues in this function, possibly when the dest pointer is accessed directly when it is cast to uint32_t. * Coalesced the 32-bit accesses into memcpy(). * Simplified the implementation to contain less variables and indices. * The function updates the source and dest pointers directly instead of using separate indices. After this, the next pixel components would be accessible using constant offsets (0-3). * It does not seem to have an impact performance-wise. * Tested on Windows, which showed the most improvement in the first CL.
