Removed some non-translatable strings and just hardcoded them in the code, like it's being done for other string separators. This also deduplicates some code by using Localization.
Used some Kotlin feature to reduce code.
This commit refactors the way `InfoItemDialog`s are generated. This is necessary because the old way used the `StreamDialogEntry` enum for most of the dialogs' content generation process. This required static variables and methods to store the entries which are used for the dialog to be build (See e.g.`enabledEntries` and methods like `generateCommands()`). In other words, `StreamDialogEntry` wasn't an enumeration anymore.
To address this issue, a `Builder` is introduced for the `InfoItemDialog`'s genration. The builder also comes with some default entries and and a specific order. Both can be used, but are not enforced.
A second problem that introduced a structure which was atypical for an enumeration was the usage of non-final attributes within `StreamDialogEntry` instances. These were needed, because the default actions needed to overriden in some cases.
To address this problem, the `StreamDialogEntry` enumeration was renamed to `StreamDialogDefaultEntry` and a new `StreamDialogEntry` class is used instead.

* Cleaned up ``getMostCompactAudioIndex`` and ``getHighestQualityAudioIndex`` into a new method ``getAudioIndexByHighestRank``
* Removed unreadable code and use Java Streams API
* Tests work as expected
Prefering video-only streams to video streams for our player will allow us to make seamless transitions on 360 and 720p qualities on YouTube.
External players and the downloader are not affected by this change.
This checks if the uploaderUrl is in the database, if not it gets the
uploaderUrl and puts it in the database. This is similar to the fetching
of uploaderUrl when it doesn't exist done in #6919.
Also use createNotification when error occurs in getStreamInfo.
