NEW PORT: emulators/qemu-user-static-devel: QEMU user-mode emulation

This port represents the to-be-released version of qemu-user-static for
testing prior to unleashing it upon the community at large and the package
building infrastructure. Currently, it is based on the bsd-user-rebase-3.1
branch that moves the base qemu version of this work forward.

The main highlight of the update to 3.1 is initial riscv64 bsd-user support,
submitted by Embecosm.

This version of the port is also notably no longer based on the master port,
qemu-sbruno, but repocopied from it due to reusing a good portion of it. As
such, it's been severely reduced to eliminate all of the bits not relevant
to building bsd-user/ (including the various port options), so much of the
diff is eliminating the option-enabled checks and combining them all into a
single CONFIGURE_ARGS/MAKE_ARGS, along with some additional --disable-flags
for things that we certainly don't need.

The python2.7 version restriction has been dropped as qemu's actually
supported py3+ since at least the 2.x version we have over in qemu-sbruno, A
follow-up commit will also drop the version restrictions in the other qemu
ports that still have it to be proactive about this stuff as Python2 reaches
EOL.

Q/A:
 * portlint: looks fine
 * testport: 11.3, -CURRENT; amd64
