Make libyuv package-friendly dependency

[novomesk]

libyuv is required by default in main. I know it can be disabled but the performance is worse without libyuv.

Problem is that libyuv doesn't have releases or tags, checkout of random commits are used.

People who maintain various build systems or distro maintainers usually don't like dependencies of this kind. More thoughts: https://wiki.gentoo.org/wiki/Why_not_bundle_dependencies

It would be ideal, if libyuv is is installed as shared library in system as any other libraries from other packages, it is versioned, it can be found via pkgconfig or cmake, sources packed in a .tar.gz archive which can be downloaded directly and with checksum that doesn't change over time.

@wantehchang FYI, as you are listed among https://chromium.googlesource.com/libyuv/libyuv/+/refs/heads/main/OWNERS

Cf. https://repology.org/project/libyuv/versions for the current packaging effort. Not ideal.

P.S. Suggested (minimal) pkg-config patches are available e.g. here.
