Introduce new pose library, based on the Asset Browser. Contrary to the old pose library (in `editors/armature/pose_lib.c`), which stored an entire library of poses in an `Action`, in the new library each pose is its own `Action` datablock. This is done for compatibility with the asset browser, and also to make it easier to attach preview images, share datablocks, etc. Furthermore, it opens the door to having animation snippets in the pose library as well. This commit contains the C code for the pose library; in order to fully use it, an addon is required as well (which will be committed shortly).
