Export logic for converting tsconfig into swcrc (or publish it as a separate NPM package)

[GreenTea124]

ts-node is able to convert tsconfig into SWC config:
https://github.com/TypeStrong/ts-node/blob/main/src/transpilers/swc.ts

Perhaps, this functionality could be exported, or extracted into a separate NPM package. It is something that would be useful in more scenarios (webpack/esbuild/vite configs and plugins).

There is a similar project already (https://github.com/Songkeys/tsconfig-to-swcconfig), bit it seems like something that deserves a large and trustworthy maintainer.
