Fix memory management for toggle-ref

(Apply commit 960f233 from 'mono_libgc' branch.)

Replace GC_free with GC_INTERNAL_FREE. The former might take the GC lock
and deadlock us.

Replace GC_INTERNAL_MALLOC with GC_INTERNAL_MALLOC_IGNORE_OFF_PAGE as
we don't need the rest of the GC messing around with the toggleref array.
