Deprecate 32 bit big-endian MIPS

It's becoming harder to maintain a cross-compiler to test this host
architecture as the old stable Debian 10 ("Buster") moved into LTS
which supports fewer architectures. For now:

  - mark it's deprecation in the docs
  - downgrade the containers to build TCG tests only
  - drop the cross builds from our CI

Users with an appropriate toolchain and user-space can still take
their chances building it.

from Linux upstream kernel, declare it deprecated.
Host Architectures
------------------
BE MIPS (since 7.2)
'''''''''''''''''''
As Debian 10 ("Buster") moved into LTS the big endian 32 bit version of
MIPS moved out of support making it hard to maintain our
cross-compilation CI tests of the architecture. As we no longer have
CI coverage support may bitrot away before the deprecation process
completes. The little endian variants of MIPS (both 32 and 64 bit) are
still a supported host architecture.
