de76ab5 added the config,
`$wgVectorDefaultSkinVersionForExistingAccounts`. Its usage in
`Hooks::onUserGetDefaultOptions()` was invoked not only for existing
accounts but anonymous users _as well._ This is a bug, due to my own
misconceptions about the hook, that went against both the config's name
and its documentation.
Unfortunately, user sessions are unavailable in
`Hooks::onUserGetDefaultOptions()` so it does not seem to be possible to
determine whether the active user is an anonymous or existing account.
This patch drops the hook and centralizes all version determination
logic in SkinVersionLookup::getVersion(). SkinVersionLookup requires a
the active User object and can make the anonymous / existing account
determination by checking login state.

Changes:
- Add the LatestSkinVersionRequirement requirement class, which lazily
evaluates the application state to get the version of the skin for the
request.
This majority of this class is taken from Stephen Niedzielski's
Vector\SkinVersionLookup class, which was introduced in d1072d0fdf.
- Register an instance of LatestSkinVersionRequirement and register the
'LatestSkin' feature that requires that requirement
- Re-introduce SkinVector::isLegacy and make it defer to the Feature
Manager

As described in the readme but not implemented until now, this patch
enables the skin version to be specified as a URL query parameter. This
is useful for testing both skin versions during development and on wiki,
as well as enabling sharing URLs with a specific skin (Vector) and skin
version (1 or 2).
Obtaining the actual skin version requires tying together three input
sources, WebRequest, User, and Config. It seems simple but it'd be easy
to botch. For this reason, a helper class to correctly interrogate them
and tests are provided.
