Resolve "Geo: Does not mark repositories as missing on primary due to stale cache"

Closes #50211 and #44044

See merge request gitlab-org/gitlab-ce!21789

I attempted to refactor so that the caller of `wrap_method` passes in a
block, rather than a method name, but I was unsuccessful.

I kept getting the following error:

NoMethodError:
        undefined method `cache_method_output' for Repository:Class

If you can figure this out, then feel free to dry up these class methods
again without doing a send-within-a-send.

* Only truthy values are cached in Redis.
* All values are cached in RequestStore and in an instance variable.

And reuse `Gitlab::Utils::StrongMemoize`.

There is a subtle behavior change required to reuse StrongMemoize in
this case. The early fallback check now occurs *before* reading the
memoized value instead of after.

I think this is fine since a memoized value should only exist if
`exists?` is also already memoized as `true`.
