Migrate the wasmtime crate to wasmtime_environ::error::*
Instead of `anyhow::Error`. This commit re-exports the `wasmtime_environ::error` as the `wasmtime::error` module, updates the prelude to include these new error-handling types, redirects our top-level `wasmtime::{Error, Result}` re-exports to re-export `wasmtime::error::{Error, Result}`, and updates various use sites that were directly using `anyhow` to use the new `wasmtime` versions. This process also required updating the component macro and wit-bindgen macro to use the new error types instead of `anyhow`. Part of #12069
