tests/tcg/multiarch: add test for plugin memory access

Add an explicit test to check expected memory values are read/written.
8,16,32 load/store are tested for all arch.
64,128 load/store are tested for aarch64/x64.
atomic operations (8,16,32,64) are tested for x64 only.

By default, atomic accesses are non atomic if a single cpu is running,
so we force creation of a second one by creating a new thread first.

load/store helpers code path can't be triggered easily in user mode (no
softmmu), so we can't test it here.

Output of test-plugin-mem-access.c is the list of expected patterns in
plugin output. By reading stdout, we can compare to plugins output and
have a multiarch test.

Can be run with:
make -C build/tests/tcg/$ARCH-linux-user run-plugin-test-plugin-mem-access-with-libmem.so

tests/tcg: add an explicit gdbstub register tester

We already do a couple of "info registers" for specific tests but this
is a more comprehensive multiarch test. It also has some output
helpful for debugging the gdbstub by showing which XML features are
advertised and what the underlying register numbers are.

My initial motivation was to see if there are any duplicate register
names exposed via the gdbstub while I was reviewing the proposed
register interface for TCG plugins.

Mismatches between the xml and remote-desc are reported for debugging
but do not fail the test.

We also skip the tests for the following arches for now until we can
investigate and fix any issues:

- s390x (fails to read v0l->v15l, not seen in remote-registers)
- ppc64 (fails to read vs0h->vs31h, not seen in remote-registers)
