ArmVirtPkg/PlatformBootManagerLib: introduce the progress bar

ArmVirtPkg's Platform BDS has never had a progress bar. We can easily add
one, by copying the PlatformBootManagerWaitCallback() function verbatim
from

  Nt32Pkg/Library/PlatformBootManagerLib/PlatformBootManager.c

It can be tested by passing the following option to QEMU (5 seconds):

  -boot menu=on,splash-time=5000
