Create benchmark perf tests for View haptics APIs 

Use android.perftests.utils.* (older version of go/androidx-bench-dev)
to create apct-tests/core/perftests tests for
View#performHapticFeedback.

Trends should be available at https://android-master-perf.skia.org.

More at go/toolkitty/benchmarks/apct-perf-tests.
