Add broadcast alarm functionality for Bosch BSD-2

[burmistrzak]

Quite an amazing feature of the Bosch smoke detectors. 🤩

By simply issuing a special Zigbee broadcast command, you'll be able to change the alarm/siren state of all BSD-2 in your network at once.
The main benefit here's that you can e.g. trigger a network-wide fire alarm when only one detector senses smoke, but also silence them all at once, except for the device that initially detected smoke.

Follow-up for #7418

To-Dos

• Improve broadcasting via sendZclFrameToAll zigbee-herdsman#1028
• Ensure adapter.sendZclFrameToAll is called correctly
• Where do we get a valid zclTransactionSequenceNumber from?

Depends on Koenkk/zigbee-herdsman#1036

Latest herdsman commit should now allow to model tz for broadcasts in the same manner as

@Nerivec Naming it zclCommandBroadcast is certainly more descriptive. 👌

Thanks!

@Nerivec @Koenkk Great work everyone! 🙌

Might be worth mentioning the behavior in the device documentation. Once I've tested the feature I can do that as well.

Nice work everybody 👍

Yep, that feature definitely needs some good docs. I believe it's really the first time, we have a command that can be sent to any one of the supported devices, to trigger something on all of them simultaneously.

Now, it all just needs to work as expected. Hopefully. 😅
Once the CI job for v19.30.0 Koenkk/zigbee2mqtt#22341 goes through, and we have a fresh container image, we'll finally know for sure. 🤞🤞🤞
