simpleperf: set kernel resources used for profiling on Android >=Q.
On Android >=Q, some debug system properties are used to set max
sample freq, cpu percentage and kernel buffer size used for recording.
This patches uses these debug properties to set needed kernel resources.
To set cpu percentage used for recording, add --cpu-percent option.
Bug: 110706031
Test: run simpleperf_unit_test.
