Add libplacebo-demos

[kasper93]

Package name

libplacebo-demos

Brief description of package

libplacebo, but the demo applications only. Main libplacebo package is a dependency of ffmpeg. We cannot build demos directly which depends on ffmpeg, creating dependency cycle as a result.

What I propose is to add libplacebo-demos package with only the demo applications.

Motivation is to give users ability to play around with those applications. Without forcing them to build locally, see haasn/libplacebo#231

URL for package's homepage

Provide a basic test case to validate the package's functionality.

It may be possible to add the demos. First, the libplacebo source need to be converted to git repository in PKGBUILD. Otherwise, the demos/3rdparty/nuklear does not exist in tarball and I got the linking error undefined reference to parse_args.

Just realized that removing ffmpeg workarounds the issue as it does not compile plplay.

[kasper93]

alternatively it could be only plplay package, other demos are not that interesting IIRC.

I have added a pull request to add the package. Would you like to test the packages from GitHub Actions artifacts of that pull request?
