CorebootPayloadPkg: Use SerialDxe in MdeModulePkg
1. Update fdf and dsc to use SerialDxe in MdeModulePkg. 2. Separate the code that gets SerialRegBase and SerialRegAccessType by CbParseLib from CorebootPayloadPkg/Library/SerialPortLib to PlatformHookLib, and then leverage BaseSerialPortLib16550 in MdeModulePkg. 3. Remove CorebootPayloadPkg/SerialDxe and CorebootPayloadPkg/Library/SerialPortLib.
