It is now managed in SimpleMpdNotifier.
This avoids unnecessary increment in AdaptationSet id counter.
Also makes sure the AdaptationSet is sorted by id in XML output.

Prefer timestamps from Video AdaptationSets if available - this avoids
possible video playback jitters due to gaps.
presentationTimeOffset is not applied to the first period as it may in
negative dts which Chrome does not like: https://crbug.com/398141.
It is safe to apply to subsequent periods as the actual offset applied
takes Period@start into consideration:
offset = Period@start - presentationTimeOffset
The result timestamp with offset applied is close to Period@start, so
it is unlikely to result in a negative dts value.
Closes b/73899306.

Also added Period::GetAdaptationSets and
AdaptationSet::GetRepresentations.
Instead of implementing GetDurationSeconds in all MpdBuilder classes
(MpdBuilder/Period/Adaptation/Representation) like what we used to do
with GetEarliestTimestamp, the two new functions allows MpdBuilder to
iterate through the Representations to get durations.
Also updates GetEarliestTimestamp functions to use the same iteration
method.

Move AdaptationSet related functions to the new Period class, which
maps to <Period> element and provides methods to add AdaptationSets.
