Fixes to javadoc and links for EarlyEntryPoint
Fixes to javadoc and links for EarlyEntryPoint

I noticed that copybara doesn't handle the transformation of links correctly when using references at the bottom of the markdown (they're all relative to "hilt/" like "hilt/https://..."), so I've inlined them until we can figure out what's up with that.

Also, noticed that the {@code} doesn't work properly when shown dagger.dev/api, e.g.
https://dagger.dev/api/latest/dagger/hilt/android/EarlyEntryPoint.html. I'm thinking this may be due to the <h1> so I switched that to <p> and switched to <code></code> since I'm not sure what's causing it.
