drivers/vpd: Add vpd_get_feature_level() API
This patch introduces the vpd_get_feature_level() API to specifically extract the "feature_level" field from the "feature_device_info" VPD key. This is used to distinguish between Chromebook-Plus and regular Chromebook devices. The previous vpd_get_feature_device_info() API is removed as vpd_get_feature_level() is enough to find VPD and extract the data. Note: The new API decodes the base64-encoded "feature_device_info" VPD data. BUG=b:324107408 TEST=Able to build and boot google/rex0.
