DynamicTablesPkg: Add SMBIOS Temperature Probe (Type 28) generator
Introduce a CM_ARCH_COMMON_TEMPERATURE_PROBE_INFO object to describe
temperature probes provided by the platform. The generator creates one
SMBIOS Type 28 record for each temperature probe object and populates
the description, location/status, probe limits, resolution, tolerance,
accuracy, OEM-defined data, and nominal value.
Add the CM object parser entry and wire the generator into the
DynamicTablesPkg build.
