Correct a few edge cases where we used the keymaps at point when
looking up keymaps for an event position which is outside the
current buffer. Namely:
- Clicking on a part of the mode line which is after the end of
mode-line-format produces an event with non-nil posn-area but
nil posn-string.
- Even if posn-string doesn't have a local keymap, we should
still ignore the keymaps at point if posn-string is non-nil.

for more positions outside the buffer. (bug#76620)
Only allow string mutation that is certain not to require string data to
be resized and reallocated: writing bytes into a unibyte string, and
changing ASCII to ASCII in a multibyte string.
This ensures that mutation will never transform a unibyte string to
multibyte, that the size of a string in bytes never changes, and that
the byte offsets of characters remain the same. Most importantly, it
removes a long-standing obstacle to reform of string representation and
allow for future performance improvements.

Add line-column tracking for tree-sitter parsers. Copied from
comments in treesit.c:
Technically we had to send tree-sitter the line and column
position of each edit. But in practice we just send it dummy
values, because tree-sitter doesn't use it for parsing and
mostly just carries the line and column positions around and
return it when e.g. reporting node positions[1]. This has
been working fine until we encountered grammars that actually
utilizes the line and column information for
parsing (Haskell)[2].
[1] https://github.com/tree-sitter/tree-sitter/issues/445
[2] https://github.com/tree-sitter/tree-sitter/issues/4001
So now we have to keep track of line and column positions and
pass valid values to tree-sitter. (It adds quite some
complexity, but only linearly; one can ignore all the linecol
stuff when trying to understand treesit code and then come
back to it later.) Eli convinced me to disable tracking by
default, and only enable it for languages that needs it. So
the buffer starts out not tracking linecol. And when a
parser is created, if the language is in
treesit-languages-require-line-column-tracking, we enable
tracking in the buffer, and enable tracking for the parser.
To simplify things, once a buffer starts tracking linecol, it
never disables tracking, even if parsers that need tracking
are all deleted; and for parsers, tracking is determined at
creation time, if it starts out tracking/non-tracking, it
stays that way, regardless of later changes to
treesit-languages-require-line-column-tracking.
To make calculating line/column positons fast, we store
linecol caches for begv, point, and zv in the
buffer (buf->ts_linecol_cache_xxx); and in the parser object,
we store linecol cache for visible beg/end of that parser.
In buffer editing functions, we need the linecol for
start/old_end/new_end, those can be calculated by scanning
newlines (treesit_linecol_of_pos) from the buffer point
cache, which should be always near the point. And we usually
set the calculated linecol of new_end back to the buffer
point cache.
We also need to calculate linecol for the visible_beg/end for
each parser, and linecol for the buffer's begv/zv, these
positions are usually far from point, so we have caches for
all of them (in either the parser object or the buffer).
These positions are far from point, so it's inefficient to
scan newlines from point to there to get up-to-date linecol
for them; but in the same time, because they're far and
outside the changed region, we can calculate their change in
line and column number by simply counting how much newlines
are added/removed in the changed
region (compute_new_linecol_by_change).

Among other users, let-alist widely uses symbols which start with a ".".
Make those symbols print more nicely by tweaking the escaping rules in
print_object to not escape a leading "." followed by a letter. This is
a conservative change to avoid constraining future lexer changes.
This is a followup to 637dde4aba, which
removed some unnecessary escaping of "." and "?" when printing symbols
in prin1. (Actually, if we always escaped "?" (which was the case
before 637dde4aba) then "." only ever needs to be escaped when
string_to_number returns non-nil. So 637dde4aba could have just
dropped the escaping of "." with no other changes, if it didn't also
remove escaping of "?")

1. Prefer "native-compiled" to "native compiled".
The adjective "native-compiled" with the hyphen is generally more
consistent with the typical pattern in English, especially when the
compound modifies a noun (e.g., "native-compiled code").
2. Prefer "natively compiled" to "natively-compiled".
The adverb "natively" modifies "compiled", and it is standard not
to hyphenate an adverb + adjective combination when the adverb ends
in -ly (e.g., "code that is natively compiled").
For example, note that we say "high-speed internet" but "highly
performant code".
