- Import cmdcnst.h and vga.h headers from the 'vga_new' VGA Miniport Driver, that contain definitions related to VGA registers as well as command-stream functionality. - Replace a bunch of hardcoded values by their corresponding defintions. - Replace "Captain-Obvious" comments in VgaIsPresent() with actual explanations from the corresponding function in 'vga_new'. - Simplify the VgaInterpretCmdStream() function, based on the corresponding one from 'vga_new'. - Use concise comments in the 'AT_Initialization' command stream definition. - Import the 'VGA_640x480' initialization command stream from 'vga_new' and use it as the full VGA initialization stream whenever the HAL does not handle the VGA display (HalResetDisplay() returning FALSE). Otherwise we just use the 'AT_Initialization' command stream that performs minimal initialization. - Remove unused AT_Initialization and other declarations from ARM build.
