drivers/intel/fsp2_0: Add API to convert BMP images to GOP BLT buffer

This patch adds an API to convert BMP images into GOP BLT buffers for
Intel FSP-S. This is required to display the OEM splash screen at
pre-boot phase.

Previously, Intel FSP-S had provision to consume the *.BMP file as is.
However, starting with the Alder Lake platform, Intel FSP has dropped
this conversion logic and expects the boot firmware to pass the BLT
buffer directly.

This patch implements the conversion logic in coreboot.
