The `toBundle()` method is implemented incorrectly as it uses
`parcelable` implementation to bundle `Format.metadata`.
The `parcelable` is not compatible and is likely to cause crashes if
a new field is added or removed.
Moreover, the `fromBundle` method is likely unused as in session
module the exception is [unbundled](df887a9422/libraries/session/src/main/java/androidx/media3/session/PlayerInfo.java (L1021)) as `PlaybackException`.
This is a non breaking change as all the calls to `toBundle()` and
`fromBundle` will now go to the parent class `PlaybackException`.
If this specific bundling is required in future then `Format.Metadata`
and all the `Metadata.Entry` classes need to provide `toBundle()`
and `fromBundle()` method.
