OvmfPkg/PlatformBootManagerLib: display boot option loading/starting

Consume PlatformBmPrintScLib, added earlier in this series. When
BdsDxe+UefiBootManagerLib report LoadImage() / StartImage() preparations
and return statuses, print the reports to the UEFI console. This allows
end-users better visibility into the boot process.
