Enroll a user on a credential provider.
This function enrolls and deletes a user profile using this credential provider.
If a user profile is successfully enrolled, it calls the User Manager Protocol
function Notify() to notify the user manager driver that credential information
has changed. If an enrolled user does exist, delete the user on the credential
provider.

user profile handle. Either the user profile cannot enroll
on any user profile or cannot enroll on a user profile
other than the current user profile.
@retval EFI_UNSUPPORTED This credential provider does not support enrollment in
the pre-OS.

error.
