gl/vk/rsx: Refactoring; unify texture cache code gl: Fixups - Removes rsx::gl::texture class and leave gl::texture intact - Simplify texture create and upload mechanisms - Re-enable texture uploads with the new texture cache mechanism rsx: texture cache - check if bit region fits into dst texture before attempting to copy gl/vk: Cleanup - Set initial texture layout to DST_OPTIMAL since it has no data in it anyway at the start - Move structs outside of classes to avoid clutter
