revset: introduce an API that avoids `formatspec` input serialization
Instead of having the data fully serialized, the input can be directly inserted
in the tree at a later stage.
Just using it for simple "%ld" case provide a significant boost. For example
here are the impact on a sample discovery run between two pypy repositories
with arbitrary differences (using hg perfdiscovery).
$ hg perfdiscovery
