OvmfPkg/LsiScsiDxe: Install stubbed EXT_SCSI_PASS_THRU

Browse Source 
Partially implement LsiScsiControllerStart() and LsiScsiControllerStop()
to insert the scaffolding of EXT_SCSI_PASS_THRU functions.

v3: Squash the newline below the declaration of LSI_SCSI_FROM_PASS_THRU
v2: Remove the closing of PciIo protocol from LsiScsiControllerStop().
