Remove bailed out SSG routes from the list of SSG (#83861)
### Why?
When SSG, the pages can bail out when detected a dynamic usage. However,
the routes that bailed out were still marked as SSG, which can confuse
the users.
### How?
Remove the bailed-out routes from the SSG routes list. If there are no
more SSG routes for the dynamic route, mark it as dynamic in Build CLI.
#### Before - Has 1, 2, 3, even though they bailed.
```
Route (app) Size First Load JS
┌ ○ /_not-found 0 B 114 kB
└ ● /[id] 0 B 114 kB
├ /1
├ /2
└ /3
+ First Load JS shared by all 114 kB
├ chunks/29c57ad6b43f6070.js 75.8 kB
├ chunks/df142624801412ea.js 24.3 kB
└ other shared chunks (total) 13.5 kB
○ (Static) prerendered as static content
● (SSG) prerendered as static HTML (uses generateStaticParams)
```
#### After - No longer has 1, 2, 3, and the route is marked as dynamic.
