DynamicTablesPkg: Arm SPCR Table Generator

The SPCR generator uses the configuration manager protocol to
obtain the serial port information from the platform configuration
manager. It then updates a template SPCR table structure. This
table data is used by the Table Manager to install the SPCR table.
