Add a property to reflect the app debuggability Set a build-time config to declare app debuggability that is used as input to DICE and by apps, such as compos, that make decisions based on this state. This will make it easier to tweak the definition of debuggability and keep it consistent across dependents.

Disable kmsg when microdroid isn't fully debuggable The default behaviour is to rate limit logs from user space to kmsg so override that to disable the logging instead. This prevents logs from the microdroid system components from showing in the kernel logs while the kernel log is still output on the uart. Make it so microdroid_managed doesn't crash if it can't use /dev/kmsg. Bug: 219743539 Test: MicrodroidTests Change-Id: I68c8335176b088f2a65b6effa77d1cfb9adf1939
