[build] enable coexistence parameter build (#7540)

This commit enables defining
OPENTHREAD_CONFIG_PLATFORM_RADIO_COEX_ENABLE, which can be used by
external build system (i.e. Matter) to override the platform
defaults. This is useful for platforms having transceivers that also
support coexistence between multiple protocols (WiFi/BLE etc.)`
