ArmVirtualizationPkg: PlatformIntelBdsLib: remove ties to ARM BDS

In this patch we remove all dependencies on ARM BDS libraries. We also
remove empty and/or unneeded functions, includes, etc.

PlatformIntelBdsLib "goes back to basics" temporarily -- there are no
consoles configured, and it's practically not possible to interact with
the user interface. Bisection remains available in the sense that
"ArmVirtualizationQemu.dsc" continues to build and should boot preexistent
boot options, but user interaction does regress temporarily.

The reason for this is that it's preferable to keep this patch and the
next one separate for readability's sake -- they amount to a rewrite from
scratch.
