util/chromeos: revise description for more utility scripts in future
The description.md and README.md was explicitly made for downloading or extracting some resources, but we need to add more Chrome OS related scripts soon; so the description should be revised. Also changed README.md for better markdown style, for example - Use #, ## to replace the old '-' headers - Use code format for file names - Use code block for example of shell execution Change-Id: Icc3677fa318b03f4aee1b0f5fb13b2095f2afe64 Signed-off-by: Hung-Te Lin <hungte@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/35664 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
