xen/x86: Fix Syntax warning in gen-cpuid.py

Python 3.12.2 warns:

xen/tools/gen-cpuid.py:50: SyntaxWarning: invalid escape sequence '\s'
  "\s+([\s\d]+\*[\s\d]+\+[\s\d]+)\)"
xen/tools/gen-cpuid.py:51: SyntaxWarning: invalid escape sequence '\s'
  "\s+/\*([\w!]*) .*$")

Specify the strings as raw strings so '\s' is read as literal '\' + 's'.
This avoids escaping all the '\'s in the strings.
