tpm2: verify symmetric parms in tpm2_context_new()

This adds tpm2_get_capability_algs(), tpm2_supports_alg(), and
tpm2_test_parms(). These functions allow verifying that the TPM supports
specific algs and parameters.

When creating a new context, this checks if the TPM supports the symmetric algs
we use. If the TPM does not support the symmetric algs and parameters we
require, we log and return error.
