Dmitri Shuralyov 44decbfe70 blake2b: merge go125.go into blake2b_test.go 
The go1.25 build constraint is guaranteed to always be satisfied because
the go directive is at 1.25.0, so the separated out go125.go file is not
needed. Move the assertion that the *xof type implements the hash.XOF
interface into a _test.go file to let it happen alongside other tests
in this package.

ValarDragon 12892e8c23 blake2b,blake2s: implement BinaryMarshaler, BinaryUnmarshaler 
The marshal method allows the hash's internal state to be serialized and
unmarshaled at a later time, without having the re-write the entire stream
of data that was already written to the hash.

Fixes golang/go#24548
