Amend the Serial Port Console Redirection Table to enable (i.a.) Microsoft Windows Emergency Management Services (EMS) over the serial port.

This patch replaces the Spcr.asl file which described the SPCR table in TDL format with Spcr.aslc which allows more flexibility by way of permitting the use of PCDs. This means the serial port usage can be modified at build, so a UART other than the UEFI Trace port can be specified.
