Auto merge of #103503 - thomcc:tvos-support, r=workingjubilee
Support Apple tvOS in libstd This target has existed in the compiler for a while, was `no_std`-only previously (even requiring `#![feature(restricted_std)]`). Apple tvOS is essentially the same as iOS, down to using the same version numbering, so there's no reason for this to be a `no_std`-only target the way it is currently. Not yet tested much (I have an Apple TV, but haven't tested that this can deploy and run programs on it, nor the simulator). Uses the implementation strategy as the watchOS support in #98101 and etc. That is, no `std::os::` interfaces aside from those in `std::os::unix`. Includes an update to libc in order to pull in rust-lang/libc#2958.
