Dali2 input device events (#25029)

* DALI: decode and publish DALI-2 input device event messages

Input devices such as push buttons (IEC 62386-301), occupancy sensors
(303) and light sensors (304) communicate with 24-bit event messages.
Tasmota logged these frames at log level 4 and discarded them, so it
could not react to any DALI-2 switch or sensor on the bus.

Decode the 24-bit frame according to the five IEC 62386-103 addressing
schemes and publish the result for rules and MQTT, for example

  {"DALI":{"Event":"0x82840B","Scheme":"Instance","Type":1,"Instance":1,
           "Info":11,"Name":"LongPressRepeat"}}

Push button events carry the part 301 event name, occupancy events the
Movement/Occupied/Repeat/Sensor flags and light sensor events the
Illuminance value. 24-bit frames with bit 16 set are commands from
another application controller and are ignored.

Tested with a zencontrol zc-switch rotary on an ESP32-S3-Pico with the
Waveshare Pico-DALI2, driving one channel of a DA4-T DT6 driver via
rules.

* DALI: commission DALI-2 control devices and query their instances

Control devices (IEC 62386-103) such as push buttons and sensors are
addressed with 24-bit frames and have their own short address space,
separate from control gear. Until now they could only be commissioned
by hand with raw DaliSend255 frames.

Add DaliDeviceScan 1|2[,<max_count>] which assigns short addresses using
the 24-bit INITIALISE / RANDOMISE / COMPARE / PROGRAM SHORT ADDRESS
sequence. The existing binary search used by DaliScan is shared through
a device flag so control gear commissioning is unchanged. Mode 2 probes
the bus first so addresses already in use are never reassigned.

Add DaliDevice which lists addressed control devices, reports one
device's version, status and instances (type, enabled, event scheme),
and sets the event scheme of all its instances, for example

  {"DaliDevice":{"Device":1,"Version":"2.0","Status":0,"Instances":[
    {"Instance":0,"Type":1,"Name":"PushButton","Enabled":1,"Scheme":"Instance"}]}}

Input devices default to the Instance event scheme which carries no
short address, so DaliDevice <device>,2 switches them to DeviceInstance
events that identify the sending device.
