Introduce functions required to perform a p2m context switch during a vCPU
context switch.

This patch series originally depended on a single patch (Patch 1) from [1].
To avoid introducing a dependency on the larger patch series [1],
that patch was cherry-picked into the current series, since it is the
only true dependency.

Patch 2 is fully independent.

Patch 3 depends on Patch 1.

But its versioning is now broken. A v2 of that was already posted, and now
we have a (newer) v1, with a revision log claiming it's v3.
