Add summing mode to TraceSectionMetric

Test: TraceSectionMetricTest
Relnote: """
Added TraceSectionMode("label", Mode.Sum), allowing measurement of
total time spent on multiple trace sections with the same label. For
instance, TraceSectionMetric("inflate", Mode.Sum) will report a metric
`inflateMs` for the total time in a trace spent on inflation.

Also removed API requirement, as TraceSectionMetric works together
with androidx.tracing.Trace back to lower API levels, with the use of
[forceEnableAppTracing](https://developer.android.com/reference/androidx/tracing/Trace#forceEnableAppTracing()).
"""

Additionally adds tracing of cache_miss and cache_hit for observing
cost of shader compilation for b/231455742
