platform/chrome: cros_ec_typec: Parameterize cros_typec_cmds_supported()

cros_typec_cmds_supported() is currently being used to check only one
feature flag.
Add a new feature parameter to it so that it can be used to check
multiple feature flags supported in cros_ec.
Rename cros_typec_cmds_supported() to cros_typec_feature_supported().
