types/wlr_buffer: split wlr_client_buffer_import function

`wlr_client_buffer_import` is splitted in two distincts function:
	- wlr_buffer_from_resource, which transforms a wl_resource into
	  a wlr_buffer
	- wlr_client_buffer_create, which creates a wlr_client_buffer
	  from a wlr_buffer by creating a texture from it and copying its
	  wl_resource
