This commit introduces support for the semi-popular TOML
config-format[1] through a new major-mode: toml-ts-mode.
I've read through the full spec[2], and from what I can see this
major-mode should provide correct syntax-highligting for every sort of
config-declaration which adheres to the specification.
Besides that it also adds support for imenu and basic tree-sitter
based navigation.

Add improved tree-sitter navigation
This new set of functions (and tests) should eliminate
defun-navigation bugs and limitations we currently have. This commit
doesn't change any existing bahavior: treesit-beginning/end-of-defun
and friends are unchanged. The plan is to later switch gear and
replace the current functions with the new ones introduced in this
change.
This is a relatively big change, but I've setup a comprehensive test,
and it should fix current bugs, so I think it's ok to put it on the
release branch.
The gist of the new navigation is to use treesit--defuns-around to
find the previous sibling defun, next sibling defun, and the parent
defun, then use this information to move to previous/next
beginning/end of defun in treesit--navigate-defun.
I also added comprehensive testing that tests all four possible
operations (prev-beg, next-beg, prev-end, next-end) starting at all
possible positions (between two sibling defuns, inside a sibling
defun, etc).

Unset the weight/slant/width in the spec when realizing a font
Between commits bf0d3f76dc (2014) and 6b1ed2f2c9 (2022),
realize_gui_face called font_load_for_lface with an empty or
partly emptied font spec, i.e. it ignored a part of its attrs
argument. The rationale given in bug#17973, which led to bf0d3f76dc, is not clear. However, 6b1ed2f2c9, which passes
the full font spec to font_load_for_lface and
font_find_for_lface, leads to suboptimal font choices, for
example when the font chosen for the default face has a
weight, slant or width that is not supported by other
available fonts on the system, such as 'medium' or 'heavy'.
If these attributes are not unset here, the call to
font_list_entities in font_find_for_lface arbitrarily limits
the candidate font list to those that are perfect matches for
these attributes, which means that the scoring mechanism is
bypassed. Note that the size attribute in spec is also unset,
in font_find_for_lface.
Also allow unsetting the other attributes, for debugging purposes.
