swc: Initial integration (#8847)

Hi. I'm the creator of the swc project. It stands for speedy web
compiler.

https://swc.rs

SWC is used by some famous open-source projects like next.js, Parcel
(v2), and Deno.
Lots of web developers use SWC indirectly via those open-source
projects, and lots of web developers use `@swc/core` directly.
These users include ByteDance, Tencent, Shopify, Discord, Slack, and
vscode
