MdeModulePkg: Upstream SerialDxe from EmbeddedPkg
This Serial driver layers on top of a Serial Port Library instance
to produce serial IO protocol.
There is also another SerialDxe implementation in CorebootPayloadPkg,
but SerialDxe from EmbeddedPkg should be better that also consumes
the extended interfaces GetControl/SetControl/SetAttributes in
EmbeddedPkg/Include/Library/SerialPortExtLib.h for serial IO protocol.
And the extended interfaces GetControl/SetControl/SetAttributes in
EmbeddedPkg/Include/Library/SerialPortExtLib.h has been upstream to
MdePkg/Include/Library/SerialPortLib.h.
