store: directly pass the filesize in the `details` of revlog

The dictionary only contains 1 (or 0) entries, we can directly store that
information (or None).

Moving to a simpler argument passing result in a noticable speedup (because
Python)

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.
