ArmVirtPkg/PlatformBootManagerLib: rebase boot logo display to BootLogoLib 

In the course of porting ArmVirtPkg to the MdeModulePkg BDS, commit
1f73aef50c

  ArmVirtPkg/PlatformBootManagerLib: add EnableQuietBoot & DisableQuietBoot

open-coded the EnableQuietBoot() function (and its dependencies / friends)
from IntelFrameworkModulePkg BDS.

This code duplication can be avoided; the functionality is available from
the following three libraries in MdeModulePkg:

- BootLogoLib: provides the BootLogoEnableLogo() function. It does not
  provide the internal ConvertBmpToGopBlt() function -- that one is
  delegated to ImageDecoderLib (function DecodeImage()).

- ImageDecoderLib: a general library that registers decoder plugins for
  specific image formats, and provides the generic DecodeImage() on top.

- BmpImageDecoderLib: one of said decoder plugins, for handling BMP images
  (which is the format of our logo).

In this patch, we revert 1f73aef50c, and atomically incorporate the
above libraries. This is inspired by Nt32Pkg commit 859e75c4fc42:

  Nt32Pkg: Use BootLogoLib for logo and progress bar drawing.
