Support MAC address as the identifier for bluetooth devices

[stackia]

This PR adds device_address (which is the MAC of Bluetooth devices) as a matchable device identifier.

(pqrs-org/cpp-osx-iokit_hid_device#1 should be merged as a prerequisite)

device_address is usually helpful for Bluetooth mouse/keyboards when the manufacturer doesn't send a valid vendor_id / product_id. For devices that have conflict vendor_id / product_id, we can also use device_address to distinguish between them (location_id can achieve the same thing, but MAC address should be more straightforward for users).

For example, we can now use such conditions in manipulators to match a device with a given MAC address.

    "manipulators": [
        {
          "type": "basic",
          "conditions": [
            {
              "type": "device_if",
              "identifiers": [
                {
                  "device_address": "ec-ba-73-21-e6-f4"
                }
              ]
            },

The setting UI has also been updated to reflect the change:

(The H (Adafruit Industries) above has vendor_id/product_id both set to 0, so only device_address is displayed.)

This may fix these related issues:

• How to allow Vendor ID & Product ID are zero #1862
• Logitech Harmony Hub not remapping (Vendor ID / Product ID are zero) #163
• Issues with multiple devices with different "location_id" but same "vendor_id" and "product_id" #3405
• ZMK board not been recognized properly #3236

This needs to be changed because it returns a pointer to data on the stack.

Sorry, I misunderstood and this code is fine.
(I misunderstood it as device_properties::get_device_address)

Thanks!
I'll add small changes before merging. Please wait for a while.

I've identified a problem with Magic Mouse and Magic Keyboard not getting the device address properly, so I'm trying to fix it.

[tekezo]

Magic Mouse and Magic Keyboard support will be available soon.
I'll fix the cpp-osx-iokit_hid_device.

@stackia
I've merged and released v14.12.2.
Please confirm it!

Thanks @tekezo !

I just checked v14.12.2 works great for my BLE keyboards!

[tekezo]

If device-specific Simple Modifications had already been registered in previous versions, they were hidden in the Settings UI.
I'll fix the issue.

FYI: My BT devices also have Vendor ID and Product ID, so I have been able to configure them using the previous Karabiner-Elements.

When device_address is newly appended in device_identifiers, it will be judged as a different device from the previous one, so I will modify the policy to use device_address only when Vendor ID and Product ID cannot be taken or are zero.

@stackia
Adjustments have been made in v14.12.3 to the handling of device_address as described above.
I don't think the device_address handling will change much anymore. Please check again!

Thanks, I tried 14.12.3 and it looks good so far!
