[PATCH] bootstrap: include string/vector before abort redefinition

[Nikhil Benesch via Gcc-patches]

Similar to 1467a5c and PR 98412. Bootstrapping on FreeBSD 12.2 with the
default compiler (Clang 10.0.1) fails if the <string> and <vector>
headers are included after abort is redefined to fancy_abort.
Appears to be missing defines in the new C++ module code. The following
patch is sufficient.

gcc/cp/ChangeLog:

        * module.cc: INCLUDE_STRING, INCLUDE_VECTOR.
