Alex Crichton ce2087692f Add a new wasm32-wasip3 target to Rust
This commit adds a new tier 3 target to rustc, `wasm32-wasip3`. This
follows in the footsteps of the previous `wasm32-wasip2` target and is
used to represent binding to the WASIp3 set of APIs managed by the WASI
subgroup to the WebAssembly Community Group.

As of now the WASIp3 set of APIs are not finalized nor standardized.
They're in the process of doing so and the current trajectory is to have
the APIs published in December of this year. The goal here is to get the
wheels turning in Rust to have the target in a
more-ready-than-nonexistent state by the time this happens in December.

For now the `wasm32-wasip3` target looks exactly the same as
`wasm32-wasip2` except that `target_env = "p3"` is specified. This
indicates to crates in the ecosystem that WASIp3 APIs should be used,
such as the [`wasip3` crate]. Over time this target will evolve as
implementation in guest toolchains progress, notably:

* The standard library will use WASIp3 APIs natively once they're
  finalized in the WASI subgroup.
* Support through `wasi-libc` will be updated to use WASIp3 natively
  which Rust will then transitively use.
* Longer-term, features such as cooperative multithreading will be added
  to the WASIp3-track of targets to enable using `std::thread`, for
  example, on this target.

These changes are all expected to be non-breaking changes for users of
this target. Runtimes supporting WASIp3, currently Wasmtime and Jco,
support WASIp2 APIs as well and will work with components whether or not
they import WASIp2, both WASIp2 and WASIp3, or just WASIp3 APIs. This
means that changing the internal implementation details of libstd over
time is expected to be a non-breaking change.
