fix [#32384] Submenu hotkeys not working at all since 2.6x

code cleanup:
use an enum typedef for button types. it was quite annoying debugging UI code since the defines are bit-shifted. GDB would show but->type as 13824 and blender define was (27 << 9).

fix [#32518] Vertex slide crash sometimes.

Undo would leave BMEditMesh->me pointer NULL, this would likely crash EDBM_verts_mirror_cache_begin() too.

Rather then restore 'me', remove the pointer altogether and use BMEditMesh->ob->data to save us having to keep track of 2 pointers.

code cleanup: use BMEdit_FromObject() rather then me->edit_btmesh in more places.

code cleanup: use more specific args

when pressing `play` report when the first frame can't be found.

code cleanup: use single define for undo string size, was 64 mostly, but 512 in the UI.
