Fix crash on MS-Windows due to memory-allocation problem in treesit.c

Browse source 
* src/treesit.c (treesit_load_language): Use 'xstrdup'/'xfree'
instead of 'strdup'/'free', to prevent crashes on MS-Windows,
where we must use our own implementation of 'malloc'/'free',
whereas 'strdup' uses the default implementation in the MS-Windows
C runtime library.
