soc/intel/meteorlake: 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 pre-boot splash screen while booting google/rex.
