When treesitter is enabled, by default syntax groups are not defined, but these
groups are used to identify where to skip matches in matchit and matchparen.

This patch does three things:
1. If syntax is enabled regardless of treesitter (`vim.bo.syntax='on'`):
   Use original implementation.
2. If treesitter is enabled and syntax is not:
   Match the syntax groups (i.e. `comment\|string`) against treesitter captures
   to check for skipped groups.
3. Add an explicit treesitter syntax for marking captures to skip:
   matchit uses `b:match_skip` to determine what counts as skippable
   Where 's:comment\|string' uses a match of the named syntax groups against
   a regex match of comment\|string, 't:comment\|string' now uses vim regex
   to match against the names of the treesitter capture groups.

Set the "matchparen_disable_cursor_hl" config variable to disable
highlighting the cursor with the MatchParen highlighting group.

Problem:  The matchparen plugin is slow on a long line.
Solution: Don't use a regexp to get char at and before cursor.

Example:

```vim
  call setline(1, repeat(' foobar', 100000))
  runtime plugin/matchparen.vim
  normal! $hhhhhhhh

runtime(matchparen): fix :NoMatchParen not working (vim/vim#14797)

Problem:  Changing buffer in another window using win_execute() causes
          it to show matchparen (after 9.0.0969).
Solution: Delay highlighting with SafeState in BufWinEnter.

Problem:  matchparen highlight not cleared in completion mode
Solution: Clear matchparen highlighting in completion mode

Remove hard-coded hack in insexpand.c to clear the :3match before
displaying the completion menu.

Add a test for matchparen highlighting. While at it, move all test tests
related to the matchparen plugin into a separate test file.

matchparen: do not use hard-coded match id (vim/vim#13393)

* matchparen: do not use hard-coded match id

Instead of using the hard-coded match id 3, which may also be used by
other plugins, let the matchparen plugin use whatever ids are
automatically returned when calling matchaddpos().

For backwards-compatibility, keep the `:3match` call, which will still
use the hard-coded id 3 (as mentioned in :h :3match).

Farewell to Bram and dedicate upcoming Vim 9.1 to him (vim/vim#12749)

https://github.com/vim/vim/commit/e978b4534a5e10471108259118c0ef791106fd92

Also update the header for the following files that were converted to Vim9
script upstream:

- autoload/ccomplete.lua (vim9jitted)
- ftplugin.vim
- ftplugof.vim
- indent.vim
- indent/vim.vim
- makemenu.vim

This also updates the "Last Change" dates, even if some changes (due to rewrites
to Vim9 script) were not ported.

There's still a few other places where Bram is still mentioned as a maintainer
in the files we and Vim have:

- ftplugin/bash.vim
- indent/bash.vim
- indent/html.vim
- indent/mail.vim
- macros/accents.vim
- macros/editexisting.vim
- syntax/bash.vim
- syntax/shared/typescriptcommon.vim
- syntax/tar.vim
- syntax/typescript.vim
- syntax/typescriptreact.vim
- syntax/zimbu.vim

Maybe future patches will address that.

Also exclude changes to .po files that didn't apply automatically (the
`:messages` maintainer string isn't used in Nvim anyway).
