locked narrowing if the region size is <= 0.
treesit-comment-start/end is unnecessary because of
comment-start/end-skip, so they should be removed.
Cleanup and set comment-start/end-skip for tree-sitter C-like major
modes.
I replaced the [ \t]* part in comment-start-skip with (syntax
whitespace), which is what comment-end-skip uses. I also added
grouping in comment-start-skip to match that of comment-end-skip.

1. js-mode might not be able to handle typescript file
2. Now that we use separate modes for tree-sitter modes, not falling
back makes tree-sitter modes more consistent

Lisp_Marker instead of a character position. Suggested by Eli
Zaretskii.

(Fwiden, Fnarrow_to_region): Adapt accordingly.
(narrowing_lock_peek_tag, narrowing_lock_push)

* src/buffer.c (syms_of_buffer): Two new variables,
'long-line-locked-narrowing-region-size' and
'long-line-locked-narrowing-bol-search-limit', to make the locked
narrowing around low-level hooks configurable.
Increase the default value of 'long-line-threshold'. After
carefully considering the (few) bug reports about long line
optimizations, I concluded that the previous default value was too
low.

(get_locked_narrowing_zv): Two new functions.
(handle_fontified_prop, reseat): Use them.
* src/keyboard.c (safe_run_hooks_maybe_narrowed): Use them.
