Subject: [PATCH] [0.4.9][BCRYPT] Add ECDSA P256 to known algorithms CORE-16741

Add missing structs and handler in BCryptOpenAlgorithmProvider().
Fixes CORE-16741 and similar problems.

The modern internet is not waiting for ReactOS, needed to keep the RAPPS URLs working.
fix picked from:
0.4.15-dev-3603-g e0a47b7b5ffc7d8dd5b883875200b56cec8ef923 [BCRYPT] Add BCRYPT_ECDSA_P256_ALGORITHM
