fixup(ts): put ts_query_cursor_set_match_limit behind feature guard

This is a fixup for #14915, which used the above-mentioned call to
restore the behavior of the pre-release version of tree-sitter to
that of 0.19.5. However, this function was introduced after 0.19.5,
breaking distro builds that link against 0.19.5 instead of the tag
specified in neovim's build script.

Now the function should only be called when it is available _and_
needed. Once tree-sitter is bumped to 0.19.6 (when this is released),
this guard can be removed again.

Fixes #14923 (among others)
