Christopher Speck ac365c3ee5 Refactor how Mercurial runs commands that require extensions
Summary:
Currently there are a number of `--config extensions.blah=` sprinkled throughout the Mercurial APIs which aren't pleasant to look at. Additionally it turns out the `rebase` command requires the `rebase` extension which is not turned on by default. Uses of `rebase` should also be including this flag to enable the extension when it's in use.

This adds `ArcanistMercurialAPI::buildMercurialExtensionCommand()` which allows running a Mercurial command that requires an extension just by naming the extension instead of providing the full `--config..` argument.

It can be used e.g.
```lang=php
$api->execxLocalWithExtension(
  'strip',
  'strip --rev %s --',
  $rev);

$api->execxLocalWithExtension(
  'arc-hg',
  'arc-amend --logfile %s',
  $tmp_file);
```
Which produces
```lang=console
$ hg --encoding utf-8 --config 'extensions.strip=' strip --rev 82567759e2d703e1e0497f5f41363de3a1500188 --

$ hg --encoding utf-8 --config 'extensions.arg-hg=/Users/cspeckrun/Source/phacility/arcanist/support/hg/arc-hg.py' arc-amend --logfile /private/var/folders/cg/364w44254v5767ydf_x1tg_80000gn/T/6bwck66ccx0kwskw/89989-5F8JaL
```

Refs T13659

Test Plan: I ran through several scenarios of running `arc diff` and `arc land` with uncommitted changes on non-head commits, while not having the `evolve` extension enabled. Using the `--trace` argument I verified that `rebase`, `strip`, `arc-amend`, and `arc-ls-markers` were all invoked and the corresponding `arc diff` and `arc land` commands succeeded. I also ran `arc land --onto-remote default` while `arc-hg.py` raised an exception for the "remote" case and verified that the error was caught by Arcanist and displayed the error and prevented further execution. I removed the error from `arc-hg.py` and re-ran the command and verified it succeeded.
