This is a continuation of the first two patches for bug#67417.  The
c-ts-mode--prev-line-match heuristic we added is too broad, so for now
we are just adding a very specific heuristic for the else case.

* lisp/progmodes/c-ts-mode.el:
(c-ts-mode--prev-line-match): Remove function.
(c-ts-mode--else-heuristic): New function.
(c-ts-mode--indent-styles): Use c-ts-mode--else-heuristic.

1. In a compund_statement, we indent the first sibling against the
parent, and the rest siblings against their previous sibling.  But
this strategy falls apart when the first sibling is not on its own
line.  We should regard the first sibling that is on its own line as
the "first sibling"", and indent it against the parent.

2. In linux style, in a do-while statement, if the do-body is
bracket-less, the "while" keyword is indented to the same level as the
do-body.  It should be indented to align with the "do" keyword
instead.

* lisp/progmodes/c-ts-mode.el:
(c-ts-mode--no-prev-standalone-sibling): New function.
(c-ts-mode--indent-styles): Use
c-ts-mode--no-prev-standalone-sibling. Add while keyword indent rule.
* test/lisp/progmodes/c-ts-mode-resources/indent.erts: New tests.

* lisp/progmodes/typescript-ts-mode.el
(typescript-ts-mode--font-lock-settings):
Add font-lock for hash bang line.

* lisp/progmodes/js.el (js--treesit-font-lock-settings):
Add font-lock for hash bang line.

* lisp/progmodes/ruby-mode.el (ruby-syntax-before-regexp-re):
Add grouping around methods from the whitelist.
(ruby-syntax-propertize): Also look for spaces around the slash.

* lisp/xt-mouse.el (xterm-mouse-translate-1): Fix the 'event-kind'
property of mouse-movement symbols emitted by xt-mouse.
* lisp/term/linux.el (terminal-init-linux): Call 'gpm-mouse-mode'
to set up the terminal for the mouse, if needed.

* lisp/progmodes/rust-ts-mode.el (rust-ts-mode):
Set electric-indent-chars (bug#67701).

* lisp/progmodes/js.el (js--treesit-font-lock-settings):
Highlight function parameters declared using destructuring syntax.
