tests/tcg/aarch64: Extend MTE gdbstub tests to system mode

Extend MTE gdbstub tests to also run in system mode (share tests between
user mode and system mode). The tests will only run if a version of GDB
that supports MTE on baremetal is available in the test environment and
if available compiler supports the 'memtag' flag
(-march=armv8.5-a+memtag).

For the tests running in system mode, a page that supports MTE ops. is
necessary. Therefore, an MTE-enabled page is made available (mapped) in
the third 2 MB chunk of the second 1 GB space in the flat mapping set in
boot.S. A new binary, mte.S, is also introduced for the tests. It links
against boot.S and is executed by QEMU in system mode.

tests/tcg: Don't #include <inttypes.h> in aarch64/system/vtimer.c

make check-tcg fails on Fedora with:

vtimer.c:9:10: fatal error: inttypes.h: No such file or directory

Fedora has a minimal aarch64 cross-compiler, which satisfies the
configure checks, so it's chosen instead of the dockerized one.
There is no cross-version of inttypes.h, however.

Fix by using stdint.h instead. The test does not require anything
from inttypes.h anyway.
