fix(autocmd): fire TabClosed after freeing tab page

Problem: TabClosed is fired after close_buffer is called (after b_nwindows is
decremented) and after the tab page is removed from the list, but before it's
freed. This causes inconsistencies such as the removed tabpage having a valid
handle and functions like nvim_tabpage_get_number returning nonsense.

Solution: fire it after free_tabpage. Try to maintain the Nvim-specific
behaviour of setting `<amatch>` to the old tab page number, and the
(undocumented) behaviour of setting `<abuf>` to the buffer it was showing
(close_buffer sets w_buffer to NULL if it was freed, so it should be OK pass it
to apply_autocmds_group, similar to before).
