* Migrate back to `std::` stylistically This commit moves away from idioms such as `alloc::` and `core::` as imports of standard data structures and types. Instead it migrates all crates to uniformly use `std::` for importing standard data structures and types. This also removes the `std` and `core` features from all crates to and removes any conditional checking for `feature = "std"` All of this support was previously added in #407 in an effort to make wasmtime/cranelift "`no_std` compatible". Unfortunately though this change comes at a cost: * The usage of `alloc` and `core` isn't idiomatic. Especially trying to dual between types like `HashMap` from `std` as well as from `hashbrown` causes imports to be surprising in some cases. * Unfortunately there was no CI check that crates were `no_std`, so none of them actually were. Many crates still imported from `std` or depended on crates that used `std`. It's important to note, however, that **this does not mean that wasmtime will not run in embedded environments**. The style of the code today and idioms aren't ready in Rust to support this degree of multiplexing and makes it somewhat difficult to keep up with the style of `wasmtime`. Instead it's intended that embedded runtime support will be added as necessary. Currently only `std` is necessary to build `wasmtime`, and platforms that natively need to execute `wasmtime` will need to use a Rust target that supports `std`. Note though that not all of `std` needs to be supported, but instead much of it could be configured off to return errors, and `wasmtime` would be configured to gracefully handle errors. The goal of this PR is to move `wasmtime` back to idiomatic usage of features/`std`/imports/etc and help development in the short-term. Long-term when platform concerns arise (if any) they can be addressed by moving back to `no_std` crates (but fixing the issues mentioned above) or ensuring that the target in Rust has `std` available. * Start filling out platform support doc
