manywarnings: update C warnings for GCC 12
Adjust for C programs compiled by GCC 12.
(A C++ expert still needs to look at manywarnings-c++.m4.)
* build-aux/gcc-warning.spec: Add warnings introduced in GCC 12.
* m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wbidi-chars=any,ucn
and -Wuse-after-free=3. Although not enabled by -Wall or -Wextra
they seem suitable for Gnulib-using C code.
