On the PlayStation 5, set Infinity MediaSource duration for live contents

[peaBerberian]

The Playstation 5 have issues when the MediaSource's duration property is set to a very high value (playback freezes) but not when setting it to Infinity, which is what the HTML spec as of now recommends for live contents.

However setting the MediaSource's duration property to Infinity seems more risky, considering all platforms we now support, than setting it at a relatively high 2^32 value which is what we do generally.

Moreover, setting it to Infinity require us to use another MSE API, setLiveSeekableRange to properly allow seeking. We're used to MSE issues so I'm not too confident of using another MSE API for all platforms directly.

So I added a new method in compat, returning true based on a whitelist of platform for which
it has been detected that high duration values cause issues but setting it to Infinity AND playing with setLiveSeekableRange does not. It only returns true for now on the PlayStation 5.

I then rely on that method return value for performing those work-arounds. Also because now the ~2^32 work-around may appear in two places (either on the MediaSource's duration like before, or on the setLiveSeekableRange API on the PlayStation 5 to stay close to other platforms' implementation), I also factorized the function and its inner comment.
