If we call EVP_EncryptUpdate/EVP_DecryptUpdate with length 0 we should
be able to handle it. Most importantly we shouldn't get different
results if we do this compared to if we don't!
An exception is made for CCM mode which has special handling for this in
the low level cipher function.
Fixes#8675

Not needed any more, since the presence of the OSSL_FUNC_CIPHER_CIPHER
function is enough to tell that there's a custom cipher function.

This involves gcm_cipher() (providers/common/ciphers/cipher_gcm.c),
ccm_cipher() (providers/common/ciphers/cipher_ccm.c), and
tdes_wrap_cipher() (providers/common/ciphers/cipher_tdes_wrap.c)
These are generic implementations of the OSSL_FUNC_CIPHER_CIPHER
function, which returned -1 on error when they should return 0.

From providers/{common,default}/ to providers/implementations/
Except for common code, which remains in providers/common/ciphers/.
However, we do move providers/common/include/internal/ciphers/*.h
to providers/common/include/prov/, and adjust all source including
any of those header files.
