bloblist: add api to get blob with size

Browse Source 
bloblist_find function only returns the pointer of blob data,
which is fine for those self-describing data like FDT.
But as a common scenario, an interface is needed to retrieve both
the pointer and the size of the blob data.

Add a few ut test cases for the new api.
