Log generate params duration in dev (#86726)
During the request in dev, there's a time to generate params from
`getStaticPaths` or `generateStaticParams`. Include that in the request
log. Since Pages Router's `getStaticPaths` are technically "generate
params" as well, set the label to `generate-params`.
Example:
```
GET / in 0ms (compile: 0ms, generate-params: 0ms, render: 0ms)
```
