revlog: support none compression
revlog files had uncompressed revlog entries support since forever, but
it wasn't selectable or exposed explicitly. It is occassionally useful
for performance testing as it avoids the latency of zlib or zstd. It
also has the nice side effect of providing a non-default compression
engine out-of-the-box.
