Introduce LUKS2-OPAL private dm uuid prefix.

Browse Source 
LUKS2 devices with configured HW OPAL encryption (any configuration)
get activated with private dm uuid prefix LUKS2-OPAL so that we
can properly detect devices with HW OPAL encryption even with
missing LUKS2 header (detached header). Internally LUKS2-OPAL
prefix matches LUKS2 device type.
