soc/intel/alderlake: Add provision to show pre-boot splash screen
This patch adds the ability to show a pre-boot splash screen on Meteor Lake systems using FSP-S.
The patch calls into `fsp_convert_bmp_to_gop_blt()` when the `BMP_LOGO` config is enabled. This function converts a BMP file to a BLT buffer, which is then used by FSP-S to render the splash screen.
Additionally, increase the heap size (malloc'able size) upto 512KB (when BMP_LOGO config is enabled) to accommodate high resolution logo file.
BUG=b:284799726 TEST=Able to see splash screen while booting google/marasov with BMP_LOGO config enable.
