efi: Pass boot services variable info to runtime code
EFI variables can be flagged as being accessible only within boot services. This makes it awkward for us to figure out how much space they use at runtime. In theory we could figure this out by simply comparing the results from QueryVariableInfo() to the space used by all of our variables, but that fails if the platform doesn't garbage collect on every boot. Thankfully, calling QueryVariableInfo() while still inside boot services gives a more reliable answer. This patch passes that information from the EFI boot stub up to the efi platform code.
