Marc Mutz 0411d98192 QCryptographicHash: auto-calculate MaxHashLength
Add Algorithm::NumAlgorithms and use it to iterate over all
statically-available algorithms, querying their hashLengthInternal().

This avoids having to statically_assert(<= MaxHashLength) everywhere,
and auto-adjusts the buffer size in SHA1_ONLY builds.

Yes, the extra case labels for NumAlgorithms are a nuisance, but at
least the compiler will remind us when we forget, unlike a missing
static_cast(<= MaxHashLength) that might easily be forgotten.

Adjust the test (which iterates over the QMetaEnum for
QCryptographicHash::Algorithm, so finds NumAlgorithms and tries to
pass it to the hash() function which responds with a
Q_UNREACHABLE(). Only test hashLength() == 0 for that enum value.

Pick-to: 6.5
