Make treesit-search-forward-goto accept a NODE argument

Browse source 
With NODE argument we can do

(setq node (treesit-search-forward-goto node))

And we can choose what node to pass to it (maybe we want to pass it
the largest node at point, rather than the smallest node, and in case
of multiple parsers, we can choose which parser to use).

* doc/lispref/parsing.texi (Retrieving Node): Update manual.
* lisp/treesit.el (treesit-search-forward-goto): Accept a NODE
argument.

This function moves point to the start or end of the next node in
the buffer that matches @var{predicate}. If @var{start} is
non-nil, stop at the beginning rather than the end of a node.
@defun treesit-search-forward-goto node predicate &optional start backward all
This function moves point to the start or end of the next node after
@var{node} in the buffer that matches @var{predicate}. If @var{start}
is non-nil, stop at the beginning rather than the end of a node.
This function guarantees that the matched node it returns makes
progress in terms of buffer position: the start/end position of the
returned node is always greater than that of @var{node}.
Arguments @var{predicate}, @var{backward} and @var{all} are the same
as in @code{treesit-search-forward}.
