  doc: clarify raw RSA migration

RSA_private_encrypt() and RSA_public_decrypt() support both PKCS#1 v1.5
and no padding, but the migration guide currently describes their EVP
replacements as using no padding only.

Document direct mappings to EVP_PKEY_sign() and
EVP_PKEY_verify_recover(), and explain that compatibility requires no
signature digest and the same legacy padding mode, RSA_PKCS1_PADDING or
RSA_NO_PADDING.
