Test duration of hypervisor sections

Hypervisors run non-preemptible, as such, it is very desirable to never
run them for long periods of time. To track this and make sure we don't
regress, add a new test that parses hypervisor traces after a compos
run to look for outliers.

Bug: 229975925
Test: atest AVFHostTestCase#testHypervisorLongSections
