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.
