Fix VideoOut events (#2330)

* Fix event data for VideoOut events

Fix is based on some decompilation work shared by red_prig.

* Cleanup

* Oops

* Style fixes

* Clang

* Fix libSceVideoOut event idents

Based on some decompilation work, events coming from libSceVideoOut use a separate set of values for identifiers. These values are only converted to OrbisVideoOutEventId values during calls to sceVideoOutGetEventId.
For convenience, I've placed all relevant identifiers into a enum called OrbisVideoOutInternalEventId.
Thanks to @red_prig for the tips.

* Fix?

Seems like `static_cast<u32>(hint) & 0xFF == event.ident` here, and doing those right shifts on the event.ident winds up breaking stuff.
Without this change, the if always fails because event_id was getting set to 0 instead.

* Clang
