DynamicTablesPkg: Add an ET info object parser

An Embedded Trace (ET) info object is used to provide
information about an Embedded Trace Extension (ETE) or
an Embedded Trace Module (ETM) available on a platform.

The CM_ARM_ET_INFO object has already been added to the
Arm namespace objects list by a previous patch.

Therefore, update the CM Object parser to add support
for parsing the CM_ARM_ET_INFO object.
