Shane Lontis 90409da6a5 Fix provider cipher reinit issue
Fixes #12405
Fixes #12377

Calling Init()/Update() and then Init()/Update() again gave a different result when using the same key and iv.
Cipher modes that were using ctx->num were not resetting this value, this includes OFB, CFB & CTR.
The fix is to reset this value during the ciphers einit() and dinit() methods.
Most ciphers go thru a generic method so one line fixes most cases.

Add test for calling EVP_EncryptInit()/EVP_EncryptUpdate() multiple times for all ciphers.
Ciphers should return the same value for both updates.
DES3-WRAP does not since it uses a random in the update.
CCM modes currently also fail on the second update (This also happens in 1_1_1).

Fix memory leak in AES_OCB cipher if EVP_EncryptInit is called multiple times.

Fix AES_SIV cipher dup_ctx and init.
Calling EVP_CIPHER_init multiple times resulted in a memory leak in the siv.
Fixing this leak also showed that the dup ctx was not working for siv mode.
Note: aes_siv_cleanup() can not be used by aes_siv_dupctx() as it clears data
that is required for the decrypt (e.g the tag).
