As a user reported, --with=arch= did not support the newer devices,
as we forgot to update the list.
While we still have lists to update, this one can be replaced by
checking directly against the .def file.
There was another list that we didn't update - in install.texi:
https://gcc.gnu.org/install/configure.html#with-multilib-list
[We had only updated:
https://gcc.gnu.org/install/specific.html#amdgcn-x-amdhsa ]
OK for mainline - and for backporting to GCC 15?

gcn: Update --with-arch= for newer archs
Replace hard-coded list of supported devices by directly checking
config/gcn/gcn-devices.def.
gcc/ChangeLog:
* config.gcc (--with-{arch,tune}): Use .def file to validate gcn
processor names.
* doc/install.texi (amdgcn*-*-*): Update list of devices supported
by --with-arch/--with-tune.
