Revert "Remove more ifndef XFA cases"

This reverts commit 38cb7263a0923dd5613da24b18d3d7ef052ff5e3.

Reason for revert: Blocking prior revert.

Original change's description:
> Remove more ifndef XFA cases
> 
> Remove FXFT_Clear_Face_External_Stream() calls, period. This would cause
> FT to try to free memory allocated by the caller, with potentially a
> different allocator. If we're leaking, msan will find it, and we can
> deal with it properly rather than trying to force FT to tidy after us.
> 
> Always call SetView(), if we have a PDF page.  At worst, the link won't
> be used in the XFA case.
> 
> Always return 0 for the null document permissions.  If we don't have a
> document, then we can't dynamically tell if its an XFA doc, so there's
> no reason to believe it should have all permissions.  If there is an
> XFA doc under the covers, then the extension will give us the value.
