bb77c68dbd tests/tcg/aarch64: Use raw strings for regexes in test-mte.py
Use Python's raw string notation instead of string literals for regex so
it's not necessary to double backslashes when regex special forms are
used. Raw notation is preferred for regex and easier to read.

06dd94e843 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.

Python 3.12 warns:

  TEST    gdbstub MTE support on aarch64
/home/rth/qemu/src/tests/tcg/aarch64/gdbstub/test-mte.py:21: SyntaxWarning: invalid escape sequence '\('
  PATTERN_0 = "Memory tags for address 0x[0-9a-f]+ match \(0x[0-9a-f]+\)."

Double up the \ to pass one through to the pattern.
