Create another field to MeshRootCertificate's status to indicate if an error occurred

[shalier]

Bug description: If an error occurs for the MRC it would go into an error state, but that would erase what the previous state was so we wouldn't know at what state transition the error occurred. Instead, we can have another field in addition to the state field that indicates if the MRC is in progress or error and it indicates if an error occurred while not affecting the state field.

Affected area (please mark with X where applicable):

• Certificate Management [x ]

We should likely close this in favor of #5044
