tcb_svn is checked by the DCAP verifier against TcbInfo collateral and the result is reflected in tcb_status so the redundant test can be dropped. This also saves users from having to add a reference value for tcb_svn. Similarly, drop mr_seam (TDX Module hash) and rely on tcb_status for this case too (see above). While some TDX Module versions have sources/ reference values available to do reproducible builds checks, that is not the case for all environments. For now, help users and not require a reference value in RVPS for mr_seams. Signed-off-by: Mikko Ylinen <mikko.ylinen@intel.com>

As Trustee moved to use 'early' PCS TcbInfo collateral, users started seeing OutOfDate tcb_status more often. While we prefer to keep tcb_status == UpToDate as the default, give an alternative example how to relax that with an alternative check that defines a minimum acceptable TCB date.
