[OE-core][PATCH 2/2] spdx: Add SHA 512 support

[Joshua Watt <jpewhacker@gmail.com>]

Adds support for adding SHA-512 hashes (where possible). This is to
improve compliance with SBoM standards, in particular BSI TR-03181 [1].

SHA 256 hashes are still included for each file, and still used to index
files in the database. Also, while SHA 512 is supported as a hash for
downloads, most recipes are still using SHA 256 and would need to be
upgraded for full compliance with BSI TR-03183
