Fix compiling for iOS

[ryanmcgrath]

Block off the animator proxy pieces for appkit/macos to fix iOS compiling. Animation support was exploratory to begin with, and the iOS APIs are different enough that they'd need some thinking through anyway.

@madsmtm Curious if you have any idea offhand why cargo fmt would be giving inconsistent results - i.e, on my local machine it has no changes, yet CI here is complaining.

(The sheer number of files changed is also, admittedly, concerning, lol)

Nightly vs. stable rustfmt ;)

Huh. I am surprised by how much difference there is. Also, I like the rustfmt from stable more but I think that's because of the trailing commas on the last items in a struct/list/etc.

Shall we add this to CI in a new github job?

[ryanmcgrath]

Probably makes sense to do so, yeah - that way we'll know if I break it again ;)

Did this in #29 (comment) because it matched the previous output better (~= smaller diff). See rustfmt.toml for the nightly features.

Hmmm, amusingly enough I've never considered how linking something iOS-specific on a GitHub action would work. If anyone's got ideas or done it before I'm all ears, otherwise I'll have to take a look this weekend - made two basic attempts but I'm probably missing something hella obvious.

          clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is a new CI error for me. I've not used the action-rs/cargo action for iOS targets but I have done stuff with cargo-bundle and some annoying environment variables in a Makefile.

From what I can tell, the build error you got in CI is the same as what I got when I ran cargo build --example ios-beta --no-default-features --features uikit,autolayout (notice the lack of --target x86_64-apple-ios). I think it needs to be done in the args section similar to how the use-cross section of the actions-rs/cargo` references.

Closing since this was addressed/rolled in #48.
