ec/google/chromeec: Provide ec_sync wake option
The ACPI spec defines keywords for the GpioInt and Interrupt resources
to specify whether a given pin is wake capable. Some boards are using
the ec sync interrupt pin to wake the system so the CREC _CRS needs to
be updated accordingly.
Provide a new macro that allows a board to specify whether its ec sync
pin is wake capable.
BUG=b:243700486
TEST=Dump ACPI and verify ExclusiveAndWake share type is set when
EC_SYNC_IRQ_WAKE_CAPABLE is defined
