  To: devel; +Cc: Eric Dong, Chasel Chiu, Nate DeSimone

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3014

Use SerialPortTerminalLib to get console redirect after the shell is
loaded:
1. Add SerialPortTerminalLib to MinPlatformPkg/Library, add PCDs to
 configure serial port.
2. Add SerialPortTerminalLib to BdsDxe driver, to add the serial device to
 ConIn and ConOut variables
3. Include SerialDxe and TerminalDxe to CoreDxeInclude.dsc and
 CoreUefiBootInclude.fdf.
4. Use PcdSerialTerminalEnable to enable/disable this feature.
