Include HTMLFrameOwnerElement.h in fewer headers

Because HTMLFrameOwnerElement.h includes Document.h, the consequence is
mostly that Document.h includes need to be added.

Locally, this reduces the number of recompilation steps when touching
HTMLFrameOwnerElement.h from 579 to 117, and when touching Document.h
from 1214 to 1160.

There is a risk of performance regressions due to outlining
Frame::deprecatedLocalOwner().
