Add pages to view watched repos and subscribed issues/PRs (#17156)

Adds GitHub-like pages to view watched repos and subscribed issues/PRs
This is my second try to fix this, but it is better than the first since
it doesn't uses a filter option which could be slow when accessing
`/issues` or `/pulls` and it shows both pulls and issues (the first try
is #17053).

Closes #16111 
Replaces and closes #17053
