Allows presubmit_support to perform Timing and RDB reporting for each of
the lower-level "CheckXYZ" functions, provided that
ENABLE_NEW_PRESUBMIT_CHECKS is called in the PRESUBMIT.py
file that we are running. I am using the variable to avoid the breakage
caused by the similar previous CL (2332321) which was not backwards
compatible.
In addition, asks for "-realm" with ResultDB so it can maintain the
security boundary.
