rav1e: update for libgit2 1.7.x

[mascguy]

Description

Proposed update for rav1e1, updating various deps - particularly those related to libgit2 - to fix build issues.

Creating as draft, as multiple iterations may be needed.

Notifying maintainers:
@MarcusCalhoun-Lopez for port rav1e.

Interestingly enough, while CI fails, rav1e builds fine locally. (At least for macOS 11 and 12; not able to create a macOS 13 VM yet.)

Not sure what's going on, but have some theories. Stay tuned...

@lukaso Lukas, can you test with my changes from this PR?

It may still fail due to libiconv, but the issues related to libgit2 at least appear to be fixed now. (Going to tackle the libiconv issue too, but that requires more digging into what the Rust build is doing under-the-hood.)

I'm not sure how do I do that. I've got a pretty complex build flow unfortunately.

Rust has just merged this PR: rust-lang/cc-rs#848 which should improve how it handles MACOSX_DEPLOYMENT_TARGET and friends. It might just be worth waiting for the next rust release before digging in. I suspect these problems will start to ease once rust's handling is better.

I would suggest that we either finish this or close it.

Closing this for now. Feel free to re-open it when you feel you have a version you would like to commit of course.
