[PATCH 0/2] Allow individual features to be locked down

This simple change allows usecases where someone might want to  lock only specific
feature at a finer granularity than integrity/confidentiality levels allows.
The first likely user of this is the CoCo subsystem where certain features will be
disabled.

  lockdown: Switch implementation to using bitmap
  lockdown/kunit: Introduce kunit tests
