vc/google/chromeos: Add configurable compression for logo file in cbfs
This patch enables LZMA or LZ4 compression algorithm for the logo cbfs
file based on BMP_LOGO_COMPRESS_LZMA or BMP_LOGO_COMPRESS_LZ4 Kconfig.
Logo cbfs file is compressed based on CBFS_COMPRESS_FLAG, by default.
Based on logo file content and target platform, enabling LZ4 could
save significant boot time, with increase in file size.
For brox:
cb_logo LZ4 is +1265 bytes than LZMA, saves ~0.760ms in decomp.
cb_plus_logo LZ4 is +2011 bytes than LZMA, saves ~0.880ms in decomp.
BUG=b:337330958
TEST=Able to boot brox and verified firmware splash screen display
with LZMA and LZ4 compression.
