remove pParentFrame from SfxFrame

Dead as least as far back as
commit 93a7b558588be1f12e137329548b706daccc07df

[CWS autorecovery] merged SfxTopFrame into SfxFrame
SfxTopFrame was the only class deriving from the abstract class SfxFrame, so both
can effectively be treated as one class.

Arguably when that commit was done, SfxFrame should also have been renamed
to SfxTopFrame, since that it was it now seems to be.

Expanding the nullptr value off that field means that:
SfxFrame::GetTopFrame
always return this
SfxFrame::IsParent
always returns false
SfxViewFrame::GetTopFrame
is now the same as SfxViewFrame::GetFrame
SfxViewFrame::GetParentViewFrame
now returns null
