Once https://github.com/mongodb/libmongocrypt/pull/263 is complete, it should be possible to enable the “should encrypt mock data when using the CSFLE shared library” AutoEncrypter test in the libmongocrypt bindings.

AC:

• Create a script that will download the shared library for a specific MONGODB_VERSION and set the path to it as CRYPT_SHARED_LIBRARY.
• Create a separate task in Evergreen to use the download script and then run npm run check:csfle with CRYPT_SHARED_LIBRARY set in the env.
• Add this task to our PR CI Matrix
• Update the driver spec test setup to set autoEncryption.extraOptions.cryptSharedLibPath when CRYPT_SHARED_LIBRARY is present in the env.
• The existing task should be renamed so it is clear which is testing shared library and which is testing mongocryptd
• If there are any failures against shared library, file a separate ticket where those can be investigate
