The Recovery Block I/O PPI is used to access block devices. Because the Recovery
Block I/O PPIs that are provided by the PEI ATAPI driver and PEI legacy floppy
driver are the same, here we define a set of general PPIs for both drivers to use.

@par Note:
The MediaInfo structure describes an enumeration of possible block device
types. This enumeration exists because no device paths are actually passed
across interfaces that describe the type or class of hardware that is publishing
the block I/O interface. This enumeration will allow for policy decisions
in the Recovery PEIM, such as "Try to recover from legacy floppy first,
LS-120 second, CD-ROM third." If there are multiple partitions abstracted
by a given device type, they should be reported in ascending order; this
order also applies to nested partitions, such as legacy MBR, where the
outermost partitions would have precedence in the reporting order. The
same logic applies to systems such as IDE that have precedence relationships
like "Master/Slave" or "Primary/Secondary". The master device should be
in the Recovery PEIM, such as "Try to recover from legacy floppy first,
