De-tile GOB when DMA copying from block linear to pitch kind memory regions (#3207)

Browse source 
* De-tile GOB when DMA copying from block linear to pitch kind memory regions

* XML docs + nits

* Remove using

* No flush for regular buffer copies

* Add back ulong casts, fix regression due to oversight
