GPUTexture: Refactor of texture creation & new feature
- Texture creation now requires explicit data type. - GPU_texture_add_mipmap enable explicit mipmap upload. - GPU_texture_get_mipmap_size can be used to get the size of a mipmap level of an existing GPUTexture - GPU_texture_read let you read back data from a gpu texture.
