Remove gSystemHeap and use _buffersSegmentEnd instead, make buffer alignments explicit for gcc (#1901)

Browse source 
* Remove gSystemHeap and use _buffersSegmentEnd instead, make buffer alignments explicit for gcc

* ALIGNEDn -> ALIGNED(n), reposition alignment attribute for PreNmiBuff

* Correct positioning of ALIGNED for filter data in audio/lib/data.c

* Add ALIGNED to TypenameMacros

* ALIGNED(4) on same line for PreNmiBuff

* Revert audio load.c change, to be submitted separately
