Configure the crypto context in OpenFHE

This pass generates helper functions to generate and configure the OpenFHE crypto context for the given function. Generating the crypto context sets the appropriate encryption parameters, while the configuration generates the necessary evaluation keys (relinearization and rotation keys).

For example, for an MLIR function @my_func, the generated helpers have the following signatures

func.func  @my_func__generate_crypto_context() -> !openfhe.crypto_context

func.func  @my_func__configure_crypto_context(!openfhe.crypto_context, !openfhe.private_key) -> !openfhe.crypto_context
