mb/google/rambi: Fix built-in audio under Windows
Move the jack detect GpioInt resources under the codec (where they belong), but also leave a copy under LPEA for since the Linux drivers (incorrectly) require them there. Add pin list for Windows' SST driver. Adapted from the Intel ValleyView edk2 ACPI reference code. TEST=build/boot Win11, Linux on google/swanky; verify audio functional OOTB under Linux, under Windows with coolstar's drivers.
