* When initializing from a dill in the incremental compiler check that
the nnbd mode matches what we're asked to compile.
If they don't, silently do not initialize from the file.
* When serializing and deserializing, assert that the individual
libraries match the component compilation mode.
* When appending dill libraries in the CFE, assert that they match
what we're asked to compile.
* Remove NonNullableByDefaultCompiledMode.Disabled -- it's not a thing
anyway.
