The method I've used in the past is to override strings on the command
line, just like ArmVirtXen.dsc does, and I like that approach.
I like the idea of defaulting to the stable tag, though we could perhaps
shorten it to "202208" instead? I'm fairly sure the release date should
be in MM/DD/YYYY format for e.g. SMBIOS compatibility (sigh) - though
I've just realized that for SMBIOS we ignore that PCD and just use
__DATE__ and __TIME__.
