v0.21.0

This release uses the "swcx" CLI: https://github.com/swc-project/swc/discussions/3859

Thanks to help from @realtimetodie, the latest release of swc (v1.3.25) has fixes needed for us to run the "pure-rust" CLI, and avoid any node.js process running. This makes it much faster to launch many small processes. Note, our TS benchmarks in https://blog.aspect.dev/rules-ts-benchmarks already used this patch, now that it's released you should get similar performance.

BREAKING CHANGES:

We are getting close to 1.0, so this is the chance to make disruptive changes before entering a semver guarantee.

• Minimum version of swc is now v1.3.25
• An explicit version now has to be given to swc_register_toolchains; we don't silently default to latest
• the term "transpile" is not typically used in swc, so the underlying rule swc_transpile has been renamed swc_compile matching the "compile" command
