metrics: Move Wattson metric to stdlib for reusability

Move Wattson power estimate metric to Perfetto stdlib so that the code
can be re-used.

There are many use-cases for getting estimates from a trace, and the
only difference is the particular time window of interest. Leave the
time window calculation to be metric SQL file specific, but move the
generic estimation and hierarchy breakdown to stdlib.
