store: stop relying on a `revlog_type` property
We want to know if a file is related to a revlog, but the rest is dealt with
differently already, so we simplify things further.
as a bonus, this cleanup This provides a small but noticeable speedup.
The number below use `hg perf::stream-locked-section` to measure the time spend
in the locked section of the streaming clone. Number are run on various
repository and compare different steps.:
1) the effect of this patchs,
2) the effect of the cleanup series,
2) current state compared to because large refactoring.
All benchmarks are run on linux with Python 3.10.7.

### Current state compared to the pre-refactoring state
The refactoring introduced multiple string manipulation and dictionary creation
that seems to induce a signifiant slowdown
