* x64: enable VTune support by default After significant work in the `ittapi-rs` crate, this dependency should build without issue on Wasmtime's supported operating systems: Windows, Linux, and macOS. The difference in the release binary is <20KB, so this change makes `vtune` a default build feature. This change upgrades `ittapi-rs` to v0.2.0 and updates the documentation. * review: add configuration for defaults in more places * review: remove OS conditional compilation, add architecture * review: do not default vtune feature in wasmtime-jit
