remotefilelog: adapt the `debugindex` command to past API changes

Pytype was missing these problems because it's currently inferring the classes
for `filelog` and `revlog` to be `Any`.  When that's fixed, these were flagged,
so fix these first.

The `filelog` class used to subclass `revlog`, but that was changed back in
1541e1a8e87d (with most or all of the "lost" attributes being forwarded to the
embedded `revlog` attribute at that time).  These forwarded references were
dropped over time, and this command has been broken at least as far back as
68282a7b29a7 when the `version` field was dropped.  Most of the fixes were as
simple as calling the accessor for the embedded `revlog` member, but the general
delta feature detection was a bit more involved- I copied the detection for it
from `mercurial.revlogutils.debug.debug_revlog()`.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
