…date

The DCAP update adds platform_tcb_date, qe_tcb_date, and qe_tcb_status
fields to servtd_tdx_quote_suppl_data, growing it from 774 to 822 bytes.
The tcb_date field now contains the effective date: min(platform, qe).

- Update TD_VERIFIED_REPORT_SIZE and REPORT_DATA_SIZE to 822
- Add R_PLATFORM_TCB_DATE, R_QE_TCB_DATE, R_QE_TCB_STATUS range constants
- Update struct layout documentation with byte offsets
- Remove unnecessary pre-slicing in setup_evaluation_data()
