DynamicTablesPkg: Add SMBIOS Electrical Current Probe (Type 29) generator
Add a Configuration Manager object and parser for SMBIOS Type 29
Electrical Current Probe information.
Add a Type 29 SMBIOS generator that creates one Electrical Current Probe
structure for each Electrical Current Probe CM object. The generator
validates the probe location and status fields, publishes the optional
description string, and registers the generated table with the SMBIOS
table factory.
