ArmPlatformPkg/Bds: Got rid of RequestBootType argument

Removed "RequestBootType" argument of the "*CreateDevicePathNode()" and
"*UpdateDevicePathNode()" functions. A boolean field "Request
BootType" has been added to the BDS_LOAD_OPTION_SUPPORT structure and
is used by the "BootMenuAddBootOption()" and "BootMenuUpdateBootOption()"
functions instead.
