[Stable-8.2.9 27/45] edk2: get version + date from git submodule

[Michael Tokarev]

Turned out hard-coding version and date in the Makefile wasn't a bright
idea.  Updating it on edk2 updates is easily forgotten.  Fetch the info
from git instead.  Store in edk2-version, so this can be committed to
the repo and is present in tarballs too.
