Improve window/buffer handling code
The purpose of these changes is to improve the code handling the
display of buffers in windows, switching to previous and next
buffers in windows and restoring a previous state after quitting
or killing buffers. In particular it does:
- Add a new window parameter 'quit-restore-prev' so a window can
keep its initial 'quit-restore' parameter and undoing a sequence
of quit window operations becomes more reliable (Bug#59862).
- Optionally have 'kill-buffer' call 'quit-restore-window' for
all windows showing the argument buffer (Bug#59862).
- Add a new hook so it's possible to avoid that a window gets
deleted implicitly by functions like 'kill-buffer' (Bug#71386).
- Add a new option to make 'quit-restore-window' delete windows
more aggressively (Bug#59862).
- Immediately remove killed buffers from all windows' previous
and next buffers. For windows that are already dead, use a weak
hash table to be used by 'kill-buffer'. This avoids any special
handling of such windows by the garbage collector.
- Immediately remove 'quit-restore' and 'quit-restore-prev'
window parameters that reference killed buffers. These
parameters have no more use once their buffers got killed.
- Make sure that internal windows do not have any previous and
next buffers. This fixes a silly memory leak.
- Make sure that after set_window_buffer and some wset_buffer
calls the buffer now shown in the window does not appear in the
lists of that window's previous and next buffers. The old
behavior could make functions investigating these lists
erroneously believe that there still existed some other buffer
to switch to.

"Separate" tree-sitter parser list for indirect buffers
When create a parser for the indirect buffer, set the buffer field of
the parser to the indirect buffer, but add the parser to the base
buffer's parser list. This way, all the parsers still get buffer
updates, but indirect buffer's parsers can have different narrowing than
the parsers of the base buffer.
