Shu DingandGitHub 6b9af3e0d1 Fix fallback detection logic when multiple generateStaticParams are needed (#47982) ...

### What?

Our current logic of detecting if a route allows dynamic params or not
(`fallback`) is flawed, and this PR fixes it.

### Why?

Right now, if no `generateStaticParams` is specified we return
`fallback: undefined` during dev. However, for an app with multiple
params, it may have multiple `generateStaticParams` defined in different
levels. If some level isn't covered by any `generateStaticParams`, we
still can't determine the fallback value.

### How?

I added a naive implementation to check if all params are covered by
`generateStaticParams` in the current or inner layers.

Closes NEXT-946
