ANDROID: qki: Add consolidate config

Add a "consolidate" defconfig fragment to enable further debug options
of the GKI kernel. The "consolidate" name has a storied history, but
it's effectively a "debug" kernel.

The options enabled in the consolidate.fragment have been found to have
a good balance of additional debug features versus performance impact.
For instance, SLUB_DEBUG is not enabled due to large performance impact.
