Rename selftets/vm to selftests/mm for being more consistent with the
code, documentation, and tools directories, and won't be confused with
virtual machines.

The test va_128TBswitch.c exercises a feature only supported on PPC and
x86_64, but it's run on other 64-bit archs as well. Before this patch,
the test did nothing and returned 0 for KSFT_PASS. This patch makes it
return the KSFT codes from kselftest.h, including KSFT_SKIP when
appropriate.
Verified on arm64 and x86_64.

ARRAY_SIZE is defined in several selftests. Remove definitions from
individual test files and include header file for the define instead.
ARRAY_SIZE define is added in a separate patch to prepare for this
change.
Remove ARRAY_SIZE from vm tests and pickup the one defined in
kselftest.h.

Architectures like PPC64 support mmap hint address based large address
space selection. This test can be run on those architectures too. Move
the test from the x86 selftests to selftest/vm so that other
architectures can use it too.
We also add a few new test scenarios in this patch. We do test a few
boundary conditions before we do a high address mmap. PPC64 uses the
address limit to validate the address in the fault path. We had bugs in
this area w.r.t SLB fault handling before we updated the addess limit.
We also touch the allocated space to make sure we don't have any bugs in
the fault handling path.
