bloblist: add API for applying blobs with specified tag
Add an API to search for the blobs with specified tag and use the
hook function to apply the blob data.
Add a helper function to return the inline header size as according
to recent spec[1] updates, the actual data can be following an inline
header instead of following the TE header immediately.
