Add default implementation of Tuner HAL 1.1

This CL enables the android.hardware.tv.tuner@1.1-service
with the default implementation of Tuner HAL 1.1

The 1.0 Tuner HAL interface implementation are identical to the 1.0
default implementation.
The 1.1 new API implementation are added with *_1_1 suffix.

Note that we cast all the uint32_t id in the 1.0 Hal implementation
into uint64_t even calling the old 1.0 APIs. This makes sure
the 1.1 default implementation internally only record 64-bit ids.

Test: atest VtsHalTvTunerV1_1TargetTest
