Replace twin.macro with tailwindcss

[devrsi0n]

The main reasons we use twin.macro are we can overwrite style easier and apply variants to multiple classes at once with variant groups. Since tailwindcss is adding multiply variants support, and twin.macro output has bigger bundle size, we can use plain tailwindcss to replace twin.macro fine.

Another benefit is we can remove .babelrc.js complete to adopt the Next.js new compiler swc which brings significant build/HMR improvement.
