Add API to bulk update oem_metadata

Created new API to bulk update oem_metadata. This can be done only with
UPDATE_OEM_METADATA_PERMISSION which is signature and privileged.
Triggering bulk update of oem_metadata column will mark it as null for
rows with oem supported mime type till the next idle maintenance run
re-fetches the values from OEMMetadataService. Also added support
for OEM_METADATA update for a URI using update API.
