Some Linux ISOs may have the MBR table for compatibility reasons
for Windows. The MBR tale would contain the partition entry with
start LBA0 and whole media size. There are two methods to check
the filesystem in the CD-ROM:
1. MBR partition check (Windows)
2. Whole disk check (MAC OS)
UEFI doesn't have the MBR check for UDF and Eltorito. But it may
pass the MBR check for such table and fail to detect the filesystem
of UDF. Skip the MBR check if the MBR is added for Windows
compatiblity so that the partition driver can continue UDF and
ElTorito check.

PartitionValidMbr function's second parameter should be the
last sector of the device. For MBR partition, the block size is
sector size, i.e. 512 bytes. The original value is media block
last LBA which is counted by the media block size. And media
block size is not always 512 bytes, it may be larger which would
cause the MBR boundary check incorrect. The boundary check is
based on the partition entry start LBA and size of LBA which
are both counted by the sector number (512 bytes).

The commit adds checks for detecting GPT and MBR partitions.
These checks will ensure that the device block size is big enough to hold
an MBR (512 bytes).

Add the partition type GUID for every partition to the installed handle,
this is required per the UEFI specification.
"The firmware must add the PartitionTypeGuid to the handle of every

UEFI Spec 2.3.1.D Section 9.3.5.1 says Partitions are numbered
according to their entry in their respective partition table,
starting with 1.
Update the code for MBR partition to follow this rule.
