SampleTunerTIS HAL Process TS for SectionEvents

Currently, the HAL simply sends raw TS data when
SectionEvents are created from a TS file. This CL
will have the HAL process the TS packets and construct
sections to be sent to the SectionFilter. A slight-modified
TS protocol is used that mirrors the current implementation
for PES filters.

This CL is a replication of reverted CL 19121691.

Bug: 237323181
Test: Manually using cuttlefish and the SampleTunerTvInput.
SectionEvents should be received without the 4-byte
TsHeader or any trailing data.
