FEI: libs: Add virtual method for secondary context creation.

Browse source 
Add a new vitrual method ensure_secondary_context to the
base encoder which is only required for the FEI entrypoint, that too
only when user configures the ENC+PAK mode. ENC+PAK mode is not something
supported directly by libva or driver, but this can be enabled
from the middleware.
