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, enabling LZ4 compression could save upto
~2ms in boot time, with increase in file size ~2KB.

BUG=b:337330958
TEST=Able to boot brox and verified firmware splash screen display
with LZMA and LZ4 compression.
