Add 'const' qualifier for GC_make_descriptor bitmap argument

* include/gc_typed.h (GC_make_descriptor): Make bm pointer const
(replace GC_bitmap type with "const GC_word*").
* typd_mlc.c (GC_add_ext_descriptor, GC_make_descriptor): Likewise.
* tests/test.c (bm_huge): Make array const to test updated
GC_make_descriptor declaration.
