- Use auto in places where code clarity is improved or identical.
- Replace trivial constructors and destructors with default.
- Use true random for random generation.
- Use std::string_view where it is valid to do so.
- Apply const where it is valid to do so.
- Use references where it is valid to do so.
- Manually optimize memory usage with std::move and std::copy.
- Opt for memory efficient containers where the size is known ahead of time.

Replaces some very specific code with generic support for FFmpeg, which should last us much longer than the old way. Also improves the migration of settings, which wasn't quite working with the previous way.
When FFmpeg Encoders was originally written, FFmpeg 4.2 was still new and OBS Studio did not seem to want to update to anything newer for a while. This led to code being fine-tuned for FFmpeg 4.2, which stops working the moment OBS Studio upgrades FFmpeg. This removes the dependency on FFmpeg 4.2 hopefully, and allows using newer FFmpeg versions - or perhaps even older versions.
Additionally the nonsensical behavior of the Target Quality slider was fixed. It is now from 0 to 51, instead of from 0 to 100, and as such matches FFmpeg exactly.
While the long descriptions were useful, keeping the updated and translated is pretty much impossible. Technology moves fast and not everyone that translates the project knows a lot about technology.
Therefore the long descriptions have now been replaced with a button that opens the wiki page for the feature instead. This should drastically reduce the number of help cases, and improve the translation coverage at the same time.
Adds support for the AMD Advanced Media Framework H.264 and H.265 encoders via FFmpeg. The majority of settings are supported, and the UI/UX experience mimics that of the NVENC implementation. Various settings are left out due to their complexity and should be controlled via the custom parameters field.
Removes the NVENC entry on systems without an NVIDIA GPU by checking if the library for it can be loaded. If it can't be loaded, it's likely that the user does not have a system with NVENC capabilities - and guaranteed that they can't use the encoder as FFmpeg relies on these libraries.
Changes applied:
* Moved utility files to /util/.
* Removed unused #includes.
* Removed unused ::ffmpeg::tools function.
* Removed unused variables.
* Fixed missing parentheses in the version macro.
* Fixed missing override on virtual function overrides and removed unnecessary virtual keyword from them.
* Disabled additional warning for ATL headers on MSVC only.
* Replaced direct printf parameters with their macro equivalent.
* Replaced C-style casts with C++-style casts.
* Applied clang-format again after an earlier change to the CMake file broke the integration for it.
The levels 5.2 and above were added in a newer FFmpeg version than OBS Studio is shipping with. Ideally we'd take these options directly from FFmpeg, but that is for a future commit.
Fixes the issue where "high444p" shows as "high", and "high" shows as "main", caused by the internal option mapping never being correct across version changes. Instead of keeping our own copy of things that has to be adjusted for each FFmpeg version, it's easier to just use the FFmpeg values and names.
* "Quality" Minimum/Maximum is actually QP Minimum/Maximum
* Bitrate Limits is now just Limits
* Buffer Size and Quality Target have been moved into "Limits".
