Fix some warnings on nightly Rust (#5668)

* Fix some warnings on nightly Rust

Cargo is warning about the usage of workspace dependencies where the
workspace declaration does not mention `default-features` but the
dependency mentions `default-features`, so this explicitly turns off
default features for `cranelift-codegen` at the workspace level and
removes the explicit `default-features = false` at the manifest levels.

* Explicitly enable default feature in wasmtime

* Enable another feature
