libproc_macro: Add remaining drop functions
Remaining structures from the rust bridge that missed a drop function
now have one.
ChangeLog:
* libgrust/libproc_macro/group.cc (Group::drop): Add drop
implementation.
* libgrust/libproc_macro/group.h: Add drop prototype.
* libgrust/libproc_macro/tokenstream.cc (TokenStream::drop): Add
drop implementation.
(TokenStream__drop): Change to a call to TokenStream::drop.
* libgrust/libproc_macro/tokenstream.h: Add drop prototype.
* libgrust/libproc_macro/tokentree.cc (TokenTree::drop): Add
drop implementation.
* libgrust/libproc_macro/tokentree.h: Add drop prototype.
