Fix VTS SensorsHidl Test Failures

This CL fixes test failures by:
- Remove the deprecated 'Device Temperature' sensor from
the sensor list
- Ignoring the deprecated 'Device Temperature' sensor type
for tests
- Only accessing shared memory buffer if the shared memory
type is supported
- Return a default z-axis data value for the accel sensor type.
- Update the batch() functions argument to take an int64 timestamp
to adhere to the interface

Bug: 171940270
Test: run vts -a x86 -m VtsHalSensorsV2_0TargetTest
