cbfs: Allow controlling decompression of unverified files

This patch adds a new Kconfig that controls whether CBFS APIs for
unverified areas will allow file decompression when CBFS verification is
enabled. This should be disallowed by default because it exposes the
attack surface of all supported decompression algorithms. Make
allowances for one legacy use case with CONFIG_SOC_INTEL_CSE_LITE_
COMPRESS_ME_RW that should become obsolete with VBOOT_CBFS_INTEGRATION.
