LF-13727 [#ccc] fix Bytes alignment issue of gpu video memory node

Browse Source 
Meet split failure of video memory node when running gfxbench gles for
a long time on 8QXP, leading to GPU dump.
Move Bytes alignment to ensure to find a video memory node with
sufficient memory to avoid split failure.
