REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2229
Introduces a new library class FirmwareBootMediaInfoLib that is
used to report the firmware boot media device. A default library
instance is provided that always returns the firmware boot media
is SPI flash. For platforms with other firmware boot media
options, a board-specific instance of this library should be
used instead to provide the correct firmware boot media device
information.

FirmwareBootMediaInfoLib library class that always

this is not the case, an instance

for the platform.
