Turbopack: run styled-jsx after typescript transform (#82359)
Closes PACK-5183
Based on https://github.com/swc-project/swc/issues/10944#issuecomment-3120775091, we need to run styled-jsx after typescript
Fixes this crash
```
entered unreachable code: This visitor does not support TypeScript. This method fails for optimization purposes. Encountered in unreachable visitor: visit_ts_interface_decl
```
This has become more pressing as swc seems to have turned the debug_assertion into a proper panic/crash in recent versions (I was seeing SIGSEGV when building some app): https://vercel.slack.com/archives/C03EWR7LGEN/p1754390155508789?thread_ts=1753477535.369549&cid=C03EWR7LGEN
We now have three phases/stages:
- preprocess: to strip typescript/decorators (so to normalize the syntax)
- main: for transforms that want to operate on "standard" EcmaScript (though still with raw JSX)
- postprocess: react transform, preset-env, etc (so low level "codegen")
