ArmVirtPkg/ArmVirtQemu: drop ARM BDS and make Intel BDS the default

ARM BDS support in ArmVirtQemu has been broken since SVN r17969
("ArmPkg/BdsLib: Remove Linux loader from BdsLib") dated July 14th.

Instead of fixing this, let's get rid of the ARM BDS and LinuxLoader
altogether: they violate both the UEFI spec and the arm64 Linux boot
protocol, and lack the level of integration with the QEMU command
line that the Intel BDS has when running under ArmVirtPkg or OvmfPkg.
