Rename from_raw to from_blinded_path_and_payinfo

Similar to 8ce438c, we rename
`from_raw` function used in test/fuzzy scenarios to build
`BlindedPaymentPath` to a public function
`from_blinded_path_and_payinfo`.

This function is useful when reconstructing a blinded path based
on already serialized components.
