OVMF's Platform BDS used to have a nice progress bar (with
IntelFrameworkModulePkg BDS). We can restore it 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
