dev-util/mingw64-runtime: add 11.0.0

Tentatively remove the ssp patch. Bootstrapping using USE=ssp seems
to work both with and without libssp. The libscrypt reproducer from
the patch's old link also builds fine with this version.

Also remove two obsolete flags filters:
* -fstack-clash-protection (bug #758914): ICE was fixed, if still
  run into this then updating gcc to a newer _p* snapshot should
  sort it (alternatively, use released >=gcc-13.1.0)
* -fstack-protector* (bug #870136): mingw64-runtime-11.0.0 adds
  its own (partial) ssp support, allowing -D_FORTIFY_SOURCE=3 and
  -fstack-protector-strong without libssp. Using these to build
  Wine currently still leads to failure, but we can allow it here.
