Change tree-sitter query predicate names (bug#79687)

Latest tree-sitter library throws a syntax error if the
predicate names in a query don't end with question mark.  So we
made the following change:

:equal changed to :eq?
:match changed to :match?
:pred changed to :pred?

Old names are transparently converted to new names when
expanding patterns.

:match predicate can now take the regexp and the node in any
order: it'll figure out which is which automatically. This way
it works with current Emacs convention (regexp first), as well
as tree-sitter's match convention (regexp second).

* doc/lispref/parsing.texi (Pattern Matching): Update manuel to
use new predicate names.
* src/treesit.c:
(Ftreesit_pattern_expand):
(Ftreesit_query_expand):
(treesit_predicate_match):
(treesit_eval_predicates):
(syms_of_treesit): Use new predicate names.
* test/src/treesit-tests.el (treesit-query-api): Update test.
