perf: start preprocessing static imports before updating module graph

[patak-dev]

Description

Done with @antfu by my side 😄

We are seeing in https://github.com/sapphi-red/performance-compare, a reduction from ~1650ms to ~1350ms on M1

We still need to think about the implications, but this may be a reason why the warmup plugin from @bluwy was having such a big effect. We could see if we could even start it before.

Not sure why I didn't spot this optimization, makes sense 🚀
