swc as tsx compile backend alternative

Feature request

swc as tsx compile backend alternative

Why?

• keep-names to only be applied when name is changed evanw/esbuild#2605 Since Oct 11, 2022. esbuild seems have low interest to fix --keep-names
• ReferenceError: __name is not defined #113 (comment) ts-node support swc, and don't have same problem like esbuild
• Add path mapping support to ESM and CJS loaders TypeStrong/ts-node#1585 Since Dec 29, 2021. ts-node does't support tsconfig.paths. PR is not merged yet.

Feel free to open a PR to demonstrate that the tests pass.

My main concerns are feature parity and size. swc is much bigger than esbuild: esbuild vs @swc/core

Once we know it works, tsx should detect if swc is installed and use it only if it's installed.

Locking thread to direct further dialogue in the form of PRs.
