net: ena: enable the interrupt_moderation in driver_supported_features
Add driver_supported_features to host_host info which is a new API used to
communicate to the device which features are supported by the driver.
Add the interrupt_moderation bit to host_info->driver_supported_features
and enable it to signal the device that this driver supports interrupt
moderation properly.
Reserved bits are for features implemented in the future
