UefiPayloadPkg: Set PixelsPerScanLine property in GraphicInfo HOB

PixelsPerScanLine is required in some UEFI capable OS distribution.
To align with simple-framebuffer definition in kernel Documentation:
devicetree/bindings/display/simple-framebuffer.txt, no property node
will be introduced for PixelsPerScanLine.

Set value of PixelsPerScanLine to HorizontalResolution, as they are
identical in most cases.
