New C++ API for timestamp/duration indices

• Part of Add a timeline type for relative time #8635

What

Updated the C++ API to distinguish between absolute timestamps and and relative durations.

We've deprecated the following functions in RecordingStream, with the following replacements:

• set_time_sequence -> set_index_sequence
• set_time -> set_index_duration or set_index_timestamp
• set_time_seconds -> set_index_duration_secs or set_index_timestamp_seconds_since_epoch
• set_time_nanos -> set_index_duration_nanos or set_index_timestamp_nanos_since_epoch

TimeColumn also has deprecated functions.

Questions to reviewer

The names for the functions in TimeColumn are somewhat inconsistent with those of RecordingStream.

Other notes

I also changed/broke the C API.

Looking great! Feeling somewhat strong about not having Collection::first (see comment), but otherwise all good

Seems like a good opportunity to make things more similar to Rust? I figure you'll eventually want to move towards IndexColumn? 🤔
Not sure what the exact question to the Reviewer is here 😄. Can we make things less inconsistent?

About the naming: I added a TODO in the parent issue
