fix: refactor the EVP_PKEY_OP checks

Browse Source 
On the one hand, we have public macros that are collections of EVP_PKEY_OP
bits, like EVP_PKEY_OP_TYPE_SIG, obviously meant to be used like this:

    if ((ctx->operation & EVP_PKEY_OP_TYPE_SIG) == 0) ...

On the other hand, we also have internal test macros, like
EVP_PKEY_CTX_IS_SIGNATURE_OP(), obviously meant to be used like this:

    if (EVP_PKEY_CTX_IS_SIGNATURE_OP(ctx)) ...

Unfortunately, these two sets of macros were completely separate, forcing
developers to keep them both sync, manually.

This refactor makes the internal macros use the corresponding public macros,
and adds the missing public macros, for consistency.
