meson: allow configuring the x86-64 baseline

Add a Meson option to configure which x86-64 instruction
set to use.  QEMU will now default to x86-64-v1 + cmpxchg16b for
64-bit builds (that corresponds to a Pentium 4 for 32-bit builds).

The baseline can be tuned down to Pentium Pro for 32-bit builds (with
-Dx86_version=0), or up as desired.
