perf: benchmark command for revlog indexes

We didn't have explicit microbenchmark coverage for loading revlog
indexes. That seems like a useful thing to have, so let's add it.

We currently measure the low-level nodemap APIs. There is room to
hook in at the actual revlog layer. This could be done as a follow-up.

The hackiest thing about this patch is specifying revlog paths.
Other commands have arguments that allow resolution of changelog,
manifest, and filelog. I needed to hook in at a lower level of
the revlog API than what the existing helper functions to resolve
revlogs allowed. I was too lazy to write some new APIs. This could
be done as a follow-up easily enough.

Example output for `hg perfrevlogindex 00changelog.i` on my
