Two low-hanging fruits as optimizations for version parsing: A fast path
for release only versions and removing the regex from version specifiers
(still calling into version's parsing regex if required). This enables
optimizing the serde format since we now see the serde part instead of
only PEP 440 parsing. I intentionally didn't rewrite the full PEP 440 at
this step.
