I added a new parameter DEPTH to treesit-traverse-depth-first and 
treesit-traverse-forward-depth-first (renamed to treesit-traverse-forward).

I also realized that the slowness is due to treesit-query-capture, not the 
number of nodes we traversed. So utilizing the DEPTH parameter only has 
semantic advantage. You should compile the query (a new feature I added) and 
use the compiled query for treesit-defun-query. With that, no matter the value 
of DEPTH, jumping to defun begin/end is always fast.

I also added manual entries for traverse functions, please have a look ;-) I 
haven’t add manual for treesit-search and treesit-defun-query, etc yet.

Also merged, thanks.
