Handle loading the same ad more than once

Browse Source 
Also allow the player's prepared ad media period durations array to exceed the
length of the loaded ad URIs array, as it's possible for the player to buffer
an ad media period fully at the point where it's known that an ad is coming up
but its URI is still unknown.

* Core library:
* Fix playback issue for HLS live streams without program date time
information ([#8560](https://github.com/google/ExoPlayer/issues/8560)).
* IMA extension:
* Fix handling of repeated ad loads, to avoid ads being discarded if the
user seeks away and then back to a preloaded postroll (for example).
* Fix a bug where an assertion would fail if the player started to buffer
an ad media period before the ad URI was known then an ad state update
arrived that didn't set the ad URI.
