HWPF Attributes: Support ATTR_EXECUTION_PLATFORM

Some HWPs (e.g. special wakeup) use different registers depending on which
platform the HWP is executing on (FSP/Hostboot) to avoid arbitration problems
when multiple platforms do the same thing concurrently. This attribute allows
those HWPs to query the platform. Dean/John agree with this attribute. See
RTC task 40409 for details.
