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
Firefox repo (404418 revisions):

# Base Revsets to be used with revsetbenchmarks.py script
#
# The goal of this file is to gather a limited amount of revsets that allow a
# good coverage of the internal revsets mechanisms.  Revsets included should not
# be selected for their individual implementation, but for what they reveal of
# the internal implementation of smartsets classes (and their interactions).
#
# Use and update this file when you change internal implementation of these
# smartsets classes. Please include a comment explaining what each of your
# addition is testing. Also check if your changes to the smartset class makes
# some of the tests inadequate and replace them with a new one testing the same
# behavior.
#
# If you want to benchmark revsets predicate itself, check 'all-revsets.txt'.
#
# The current content of this file is currently likely not reaching this goal
# entirely, feel free, to audit its content and comment on each revset to
# highlight what internal mechanisms they test.
