fix(module-federation): module federation does not depend on static remotes port (#32363)

## Current Behavior
If a host does not have any remotes, it fails to serve as the
`staticRemotesPort` returns as `-Infinity`.

## Expected Behavior
When a host has no remotes, set `staticRemotesPort` to `undefined` and
use this to determine whether we should wait for it.
