config_tools: add BIOS invalid setting check

Browse Source 
1. check if VMX feature is enabled in the BIOS setting.
If disabled, board inspector will show error message.
2. check if Hyper-Threading is enabled in the BIOS setting.
If enabled, board inspector will show warning message.
3. check if VT-d is enabled in the BIOS setting.
If disabled, board inspector will show error message.

v2-->v3:
Use the class names instead of addresses, and invoke the rdmsr method
of each class.

v1-->v2:
1. For the Hyper-Threading BIOS check, update the log level to the warning.
2. For VMX invalid BIOS check, the XDS does the actual check,
the board inspector only collects information.
