drivers/intel/fsp2_0: Add configurable compression for logo cbfs file

This patch adds a new configuration option to allow the compression
algorithm for the logo cbfs file to be specified. By default, the logo
cbfs file is compressed using LZMA. However, enabling LZ4 compression
can save ~2ms of boot time when the BMP_LOGO config is enabled.

This patch verified that the logo cbfs file can be booted using either
LZMA or LZ4 compression.

BUG=b:284799726
TEST=Able to boot google/rex and verified firmware splash screen using
either LZMA or LZ4 compression.
