Retain inner-class data on incremental compile 

Ensure that metadata sourced from inner-types is not deleted when
performing an incremental compile. Prior to this commit, the source
type was searched using the `Outer$Inner` format. This is not supported
`Elements.getTypeElement` so we now convert the names to `Outer.Inner`.

Closes gh-10886
