[Proposal] Add to config most compat switches

[peaBerberian]

Based on #1510, the idea behind this proposal is to add to our config properties allowing to force toggles we for now only enable for specific devices.

The goal is to simplify the debugging of issues seen on specific devices (which is the huge majority of them), by just having to update the config in the corresponding application (as proposed by #1510).

So for example let's say that we encounter a new device where relying on the same MediaKeys instance for multiple contents may fail after a time (bug encountered on LG's WebOS, on some Panasonic TVs, and now, in issue #1464, on Philips's TitanOS), we could just initially tell application people to try setting that experimental flag.

If it fixes the issue, we will add a supplementary device check inside the corresponding compat function.

This seems faster and less bothersome to me than having to create special builds of the RxPlayer, and there our role could just be to redirect the developer seeing the issue to the right config option (as opposed to having to build a player, then link that player to the application, making sure that their CI like us etc.).
