mb/google/{brya,brox,rex}: Update ec_sync wake capability
Some of the boards use the EC_SYNC pin to wake the AP but do not
advertise the pin as wake capable in the CREC _CRS resource. Relevant
boards were determined through empirical testing and inspection of gpio
configuration.
Update the ACPI tables for rex, brya, and brox based boards to advertise
their EC_SYNC pin as wake capable.
BUG=b:243700486
TEST=-Dump ACPI and verify ExclusiveAndWake share type is set when
EC_SYNC_IRQ_WAKE_CAPABLE is defined
-Wake Aviko via keypress and verify chromeos-ec as wake source
-Wake Screebo via lid open and verify chromeos-ec as wake source
