MdeModulePkg/UfsPassThruDxe: Check for RPMB W-LUN (SecurityLun)
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1546
Currently UfsPassThru only checks for 8 common LUNs. This adds a check
for the RPMB Well-known LUN and sets the corresponding bit-mask. Further
handling of the WLUN is already present in the driver.
