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

This restores the ability to run TCG smoke tests by using our docker

the first step to making better cross-architecture testing available
straight from the source tree ;-)
