ec/google/chromeec/acpi/cros_ec: Ensure GpioInt and _PRW are mutually exclusive
Under Windows ACPI, GpioInt and _PRW must be mututally exclusive within
the scope of a device, otherwise a BSOD occurs with an ACPI_BIOS_ERROR.
To enforce this, only use _PRW when EC_ENABLE_SYNC_IRQ_GPIO is not set.
If both EC_ENABLE_WAKE_PIN and EC_ENABLE_SYNC_IRQ_GPIO are set, then
ensure that the GpioInt is flagged as ExclusiveAndWake (vs just
Exclusive) so that the CREC device is still able to wake the device
as needed.
TEST=Build/boot google/{nocturne,frostflow} to Win11 w/ sync_irq_gpio
and wake_pin both enabled.
