Reduce sensor maximum delay to 0.5 second

The VTS tests VtsHalSensorsV1_0Target tries receive 50 response with a
maximum sensor delay. Thus having a high maximum delay times out the
test easily.

Also, the tests wait for 0.5 sec "for change rate to happen". Any delay
higher than that would cause flakiness (delay settings are NOT cleaned
up between tests).

BUG: 74250258

Test: run vts -m VtsHalSensorsV1_0Target -t
SensorsHidlTest.AccelerometerSamplingPeriodHotSwitchOperation_32bit
