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.
