Promote Mac Catalyst targets to Tier 2, and ship with rustup

[madsmtm]

Promote the Mac Catalyst targets x86_64-apple-ios-macabi and aarch64-apple-ios-macabi to Tier 2, as per the MCP (see that for motivation and details).

These targets are now also distributed with rustup, although without the sanitizer runtime, as that currently has trouble building, see #129069.

Still have to do some more digging, but it seems like the issue is that we don't pass the iOSSupport libraries to CMake, as is otherwise done.

I'll try to fix this in the cmake crate, but after that, we'll still have to update bootstrap to use the newer cmake.

Linking https://github.com/leetal/ios-cmake to myself for later (might contain some of the relevant CMake configuration for this).

I've disabled the sanitizer runtimes on Mac Catalyst for now and opened #129069 for that, to get this moving forwards.
@rustbot ready

I don't think it'll fail to merge again, I've tested it by replacing the pr step in jobs.yml with the dist-apple-various step I've changed, and got a successful build here (didn't actually complete, I think since it didn't upload, but the build itself completed).
