encoders/ffmpeg: Fix fallbacks, hide handler-less encoders and clean up

* Changes the encoder name to 'streamfx-{name}' from 'streamfx--{name}' as the latter is a typo, but adds a proxy to still support the latter in bad configurations.
* Some of the warning messages have been improved in order to better support end-users, and support for the new encoder error messages has been added.
* Adds support for the is_hw argument instead of blindly relying on obs_encoder_get_caps() which actually returns the wrong values due to rerouting.
* Fixed handler-less encoders showing up in the UI outside of debug builds.
