Update ffmpeg

[Megamouse]

Updates ffmpeg based on Vita3K repo to 5.1.2.

The new ffmpeg version is more optimized overall, so this is actually useful to performance during de/encoding.
Here some random timings of mostly the same scenes on repeat:

The new commit drops the source and uses CI (see .github) and a patch with the options to build the libs.
The artifacts are created automatically on our fork in the github actions section.
The codecs seem to be the same still:

Can this be updated again? A recent change was pushed to the ffmpeg repo to have macOS prebuilt arm64 libraries, and it would be helpful for #14028

[DarthMDev]

seems to be an issue with the macOS minimum version with the newer ffmpeg update

(was built for newer macOS version (12.6) than being linked (12.0))

Maybe if we change
CMAKE_OSX_DEPLOYMENT_TARGET to 12.6?

I made a pr to address this on your fork Megamouse#15

I think bumping the Cirrus image from Monterey (12) to Ventura (13) might help.

This PR is nowhere near being considered for merge.
This won't happen until Ubuntu 18.04 is dropped.
So all of these changes are not really worth spending time on right now

Also, The libs are built with macOs latest, as proof of concept.
There is no reason to bump the macOs version in this PR.
That should happen in a seperate PR if even needed.
