ArmVirtPkg/PlatformBootManagerLib: add EnableQuietBoot & DisableQuietBoot
UefiBootManagerLib does not provide these functions, we have to implement
them. (EnableQuietBoot() puts up the nice TianoCore logo.)
OvmfPkg commits 817fb3ac2a78 and 8e8fd3037788 have extracted these
functions already,
- from "IntelFrameworkModulePkg/Library/GenericBdsLib/BdsConsole.c"
- to "OvmfPkg/Library/PlatformBootManagerLib/QuietBoot.c".
Copy the latter file, with minimal changes.
