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.
