feat(autocmd): add Recording autocmds

feat(eval): add reg_recorded()

This function is used the get the last recorded register.

style(Recording): rename handler to match suggestions

fix(RecordingLeave): send autocommand earlier

This makes the autocommand fire just before setting reg_recorded to
reg_recording, this way we clearly show that we are actually just before
actually quitting the recording mode.
