config_tools: add CPU capability checks

Browse Source 
Add CPU capability checks.
If a feature is not supported on this processor, the board inspector
will show error message because it would impact ACRN’s ability
to function properly.

v3-->v4:
Update the error messages.

v2-->v3:
1. For VMX features, split each feature as a separate property, capability
checks in XML schema will then check all those features.
2. Use the class names instead of addresses, and invoke the rdmsr method
of each class.

v1-->v2:
1. Define each register as a class inheriting the `MSR` class defined
in platformbase.py, and define each bit as fields of that class.
2. The board inspector simply collects the CPU capability and attribute,
and the XSD does the actual check
