Bumping NVIM_API_LEVEL is pretty much required after every major
release, because it's also used to correlated Lua stdlib changes to
a Nvim version.

fix #33075

Problem:  fragile setup to get (preferred) keys from key_name_entry
          (after v9.1.1179)
Solution: refactor the code further, fix a bug with "pref_name" key
          entry introduced in v9.1.1180 (Yee Cheng Chin)

The optimization introduced for using bsearch() with key_name_entry
in vim/vim#16788 was fragile as it required synchronizing a non-obvious index
(e.g. IDX_KEYNAME_SWU) with the array that could be accidentally changed
by any one adding a key to it. Furthermore, the "pref_name" that was
introduced in that change was unnecessary, and in fact introduced a bug,
as we don't always want to use the canonical name.

The bug is triggered when the user triggers auto-complete using a
keycode, such as `:set <Scroll<Tab>`. The bug would end up showing two
copies of `<ScrollWheelUp>` because both entries end up using the
canonical name.

In this change, remove `pref_name`, and simply use a boolean to track
whether an entry is an alt name or not and modify logic to respect that.

Add test to make sure auto-complete works with alt names

closes: vim/vim#16987

In Nvim there is no `enabled` field, so put `is_alt` before `name` to
reduce the size of the struct.

They were moved in Vim in patch 8.1.1989.
This change is required to port patch 9.1.1243.

Keep track of the original indexes of both TAB and K_TAB, so that there
doesn't have to be an extra table and loop for K_TAB.

Problem: Cannot disable individual captures and patterns in treesitter queries.

Solution: 
* Expose the corresponding tree-sitter API functions for `TSQuery` object. 
* Add documentation for `TSQuery`.
* Return the pattern ID from `get_captures_at_pos()` (and hence `:Inspect!`).

This actually only affects the order in which Cmdline* and Cmdwin*
autocommands are listed, and it appears that the names of Cmdwin* were
changed to CmdWin* in 8ed2dbf6e2802516501c11e72e5d6d977e6a07f3 without
explanation.

Also, remove the final NULL element from the names table.
