feat(cm): context switch MDCR_EL3 register
Currently MDCR_EL3 register value is same for all the
worlds(Non-secure, Secure, Realm and Root).
With this approach, features enable/disable settings
remain same across all the worlds. This is not ideal as
there must be flexibility in controlling feature as per
the requirements for individual world.
The patch addresses this by providing MDCR_EL3 a per world
value. Features with identical values for all the worlds are
grouped under ``manage_extensions_common`` API.
