Added BEHAVIOR_DT_DEFINE() and BEHAVIOR_DT_INST_DEFINE(), which work exactly like the DEVICE_*_DEFINE() macros, except they also register the device as a behavior by adding a pointer to it to a memory section. Added zmk_behavior_get_binding(), which works like device_get_binding() except that it only searches the devices that have been registered as behaviors. This ensures that behaviors cannot have name collisions with other devices defined by the SoC, which will be important when we remove the label property from behaviors so they are given their node names. As an added benefit, this is faster since it searches a smaller list. Some basic benchmark code I wrote indicates it takes 30-70% as long, depending on where the behavior is in the list and whether the name string is an exact pointer match. From now on, behaviors should use BEHAVIOR_*_DEFINe() instead of DEVICE_*_DEFINE(), and any code that looks up a behavior by name should use zmk_behavior_get_binding() instead of device_get_binding().
