Define dependency symbols for hashless signature algorithms

Define the dependency symbols PSA_WANT_ALG_ECDSA_ANY and
PSA_WANT_ALG_RSA_PKCS1V15_SIGN_RAW as de facto synonyms of
PSA_WANT_ALG_ECDSA and PSA_WANT_ALG_RSA_PKCS1V15_SIGN respectively: if
either one is requested, the other is set.
This makes it easier to systematically determine the dependencies of
an algorithm.
