MdePkg: ATAPI: Add ATA_CMD_MODE_SENSE6 Definition
ATA_CMD_MODE_SENSE6 is used to query certain properties of
an ATA device, including its write protection state. This
definition will be used in the next commit of this series to
query if a SCSI disk is write protected.

MdeModulePkg: ScsiDiskDxe: Query Write Protected State
Currently, only SCSI attached CDROMs are marked as read only
SCSI devices. Write failures have been seen to occur when a
read only disk is attached as a SCSI device, because the device
is never queried for its write protected state and the disk is
listed as writeable.
This adds a new mode sense query to determine if a SCSI disk is
write protected. If so, the proper BlockIO media property is set
to read only, to ensure that all layers know this is a read only
disk.
