Segregate UMA metrics for production scenarios from test scenarios.
Currently we separate the UMA metrics only by one category: whether the
device is in dev mode or not. In addition, we need to exclude the noise
from these two categories:
1. Most of our testing on MP-signed images which are performed
with autest.
2. All our hwlab tests run in non-dev mode but they use dev-signed images
with dev-firmware keys.
So this CL defines additional bit fields to represent these states and
if any of these three flags are set, the UMA metric is sent to a
DevModeErrorCodes bucket. Thus the NormalErrorCodes bucket will have only
the production errors and thus we can monitor more effectively.
