main/texstore: Split texture storage into three functions
This commit splits the texture storage into three functions: texstore_depth_stencil, texstore_compressed, and texstore_rgba. Right now this split seems artificial since we just have one function pointer per format and there is no difference between these three categories. However, this split makes it much easier to write a more general function upload path for one of these categories than the current function pointers.
