optimize Version.__init__
Version objects are created thousands of times by the check_version method of
decorators. Creation is inefficient, resulting in five calls to re.match()
that do not even use precompiled regex. The use of re.match() however is
fully redundant, as finditer() can provide the same information with a better
use of groupings. Do that and precompile the tokenization regex.
This saves about 3% in the "meson setup" run of QEMU.
