Implement functions to set and check runtime-disabled algorithms. Use
these functions when the algorithm capabilities of the TPM 2 are
advertised via the TPM2_GetCapability command. However, it is not
sufficient to just suppress runtime-disabled algorithms in the return
value of this command but also certain code paths have to be instrumented
to check for disabled algorithms since they could otherwise lead to their
usage. Users are not required nor will they always look at the returned
values of TPM2_GetCapability but should still be prevented from using
runtime-disabled algorithms.
