refactor(cm): change owning security state when a feature is disabled

SPE and TRBE don't have an outright EL3 disable, there are only
constraints on what's allowed. Since we only enable them for NS at the
moment, we want NS to own the buffers even when the feature should be
"disabled" for a world. This means that when we're running in NS
everything is as normal but when running in S/RL then tracing is
prohibited (since the buffers are owned by NS). This allows us to fiddle
with context a bit more without having to context switch registers.
