Yukihiro "Matz" Matsumoto 322642364a capi.md: document that dfree handlers must not re-enter the VM

The `dfree` callback registered via `mrb_data_type.dfree` runs from
inside GC sweep, so allocating Ruby objects, calling `mrb_funcall` /
`mrb_yield`, raising exceptions, or otherwise re-entering the VM
can trigger a recursive GC that revisits the same object and causes
double-free (see #6316). Make the rule explicit in the "Wrapping C
Structures" section.

close #6316
