Show WARNING instead of FAIL for some SCT and FWTS failures

[sunnywang-arm]

SCT and FWTS are directly based on requirements in UEFI, ACPI, SMBIOS sepcs. SystemReady is also based on these same specifications, but some absolute requirements in these sspecs are relaxed to conditional requirements in SystemReady. As a result, some SCT and FWTS failures may not be SystemReady compliance issues. The links below show the examples for reference.

• https://developer.arm.com/documentation/107981/0303/Potentially-waivable-failures-for-SystemReady-band-compliance/SCT
• https://developer.arm.com/documentation/107981/0303/Potentially-waivable-failures-for-SystemReady-band-compliance/FWTS

In this case, we would like to show WARNING instead of FAIL for SCT and FWTS failures in the final reports. Alternatively, we can create additional logs based on SCT and FWTS logs where the results corresponding to conditional requirements are overridden accordingly.
