soc/intel/alderlake: Enable LZ4 compression for logo CBFS file

This patch selects LZ4 decompression for logo CBFS file. Able to save
2ms of the boot time when HAVE_FSP_LOGO_SUPPORT config is enabled.
However, the compressed BMP logo size is increased by ~2KB.

Raw BMP Image size is ~97KB.

BUG=b:284799726
TEST=Able to see pre-boot splash screen while booting google/redrix
with 32MB (W25Q256JWEIM) SPI-Flash.
