Create a similar rollup

Add `read_to_end` method for `sys::{target}::pipe::AnonPipe`. This allows
having a more optimized version of `read_to_end` for ChildStdout.

This allows decoupling `Command::spawn` and `Command::output`. This is
useful for targets which do support launching programs in blocking mode
but do not support multitasking (Eg: UEFI).

This was originally conceived when working on rust-lang#100316

This allows getting rid of some documentation and an extra step when building a custom toolchain: https://rustc-dev-guide.rust-lang.org/building/how-to-build-and-run.html#creating-a-rustup-toolchain
and it seems likely that people will want to do this if they want rustdoc (which is also built by default).
Pull in fix for bytecodealliance/rustix#467 on
recent cargo nightlies.
Removes a few lifetimes and renames some.

Allow blocking `Command::output`

### Problem
Currently, `Command::output` is internally implemented using `Command::spawn`. This is problematic because some targets (like UEFI) do not actually support multitasking and thus block while the program is executing. This coupling does not make much sense as `Command::output` is supposed to block until the execution is complete anyway and thus does not need to rely on a non-blocking `Child` or any other intermediate.

### Solution
This PR moves the implementation of `Command::output` to `std::sys`. This means targets can choose to implement only `Command::output` without having to implement `Command::spawn`.

### Additional Information

This was originally conceived when working on rust-lang#100316. Currently, the only target I know about that will benefit from this change is UEFI.

This PR can also be used to implement more efficient `Command::output` since the intermediate `Process` is not actually needed anymore, but that is outside the scope of this PR.

Since this is not a public API change, I'm not sure if an RFC is needed or not.
