std: Get the standard library compiling for wasm64 This commit goes through and updates various `#[cfg]` as appropriate to get the wasm64-unknown-unknown target behaving similarly to the wasm32-unknown-unknown target. Most of this is just updating various conditions for `target_arch = "wasm32"` to also account for `target_arch = "wasm64"` where appropriate. This commit also lists `wasm64` as an allow-listed architecture to not have the `restricted_std` feature enabled, enabling experimentation with `-Z build-std` externally. The main goal of this commit is to enable playing around with `wasm64-unknown-unknown` externally via `-Z build-std` in a way that's similar to the `wasm32-unknown-unknown` target. These targets are effectively the same and only differ in their pointer size, but wasm64 is much newer and has much less ecosystem/library support so it'll still take time to get wasm64 fully-fledged. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
