Scan for UDF file systems on all block devices, as specified by OSTA
Universal Disk Format Specification 2.60, and install a Vendor-Defined
Media Device Path for each file system found.
The Vendor-Defined Media Device Path for the UDF file system is then
checked by UdfDxe to decide whether or not start the driver.

There are scenario when the BindingStop service of PartitionDxe driver be
re-entered.
An example will be ejecting a DVD from a SATA DVDROM and then run
"reconnect -r" under shell. In this specific case, part of the calling
stack will be:
PartitionDriverBindingStop() (PartitionDxe) ->
Stop first child handle (PartitionDxe) ->
ScsiDiskFlushBlocksEx() (ScsiDiskDxe) ->
A media change is detected (ScsiDiskDxe) ->
Reinstall of BlockIO(2) protocols (ScsiDiskDxe) ->
Entering PartitionDriverBindingStop() again (PartitionDxe) ->
Potential risk of referencing already stopped child handle (PartitionDxe)
...
The current code has potential issue of referencing of already stopped
child handle. This commit adds re-entry handling logic to resolve such
issue.

Change DiskIoDxe to produce DiskIo2 protocol when the BlockIo2 protocol is available.
Change PartitionDxe to produce BlockIo2 protocol based on DiskIo2 protocol instead of BlockIo2 protocol.
