feat(build): support additional build toolchain args

[brooksmtownsend]

Feature or Problem

This PR adds the ability to parse any unknown trailing arguments to wash build directly to the underlying build toolchain.

For example, when running wash build on a Rust project, you can simply wash build --release to build the component in release mode.

Because of this, I'm strongly leaning towards removing all of the specialized build arguments in the .wash/config.json, because it's so much more flexible to be able to specify these with the native toolchain. @ricochet thoughts?

Absolutely. If a dev wants custom config options, they should specify those with config.toml in rust, package.json for js, Makefiles etc.
