Fix commit policy stuff and anchor handling

Summary:
See discussion in D5121. Fixes T2615.

This might cause us more issues if anything is loading commit handles without passing a viewer, but I think I tested all of those cases.

Implement DiffusionMercurialContainsQuery in Diffusion

Summary:
Currently, we have no implementation, so all Mercurial commits show "None" for "Branches".

Instead, implement this method.

Fix Mercurial "Last Modified" query

Summary:
To determine when a file was last modified, we currently run `hg log ... -b branch ... file`. However, this is incorrect, because Mercurial does not interpret "-b x" as "all ancestors of the commit named x" like Git does, and we don't care about where the modification happened anyway (we always have a resolved commit as a starting point). I think this got copy-pasta'd from the History query.

Instead, drop the branch-specific qualifier and find the last modification, period.

Test Plan: Mercurial commit views of commits not on the repository's default branch are no longer broken.

Fix DiffusionMercurialHistoryQuery for file history

Summary: When querying history of a path, we should continue past branchpoints. See D5146 for more discussion.

Test Plan:
Viewing history of a file on a branch which never modified the file no longer fatals.

(Arguably we could render something like "this file was never modified on this branch" and maybe link to the branch where the branchpoint stems from, but that seems of limited use.)

Use reverse(x::y) instead of y::x in Mercurial history queries

The revset "x:0" works, but the revset "x::0" is empty. We actually want "reverse(0::x)".

You can filter Concern vs. No-Concern status

Choosing a concern filter that's not `all` implies filter `status` to be `open`
