fix(CompositeDevice): remove deadlock and perform target device work in parallel

[ShadowApex]

This change fixes a rare deadlock where a force feedback event can cause the target device to wait for a FFUpload response from the composite device while the composite device is waiting for a response from the target device about its capabilities. Requests for the capabilities of target devices will now happen asynchronously in its own task to allow the composite device to continue processing other requests.

This change also updates some of the target device handling logic to perform certain requests in parallel using a JoinSet instead of performing requests serially.

Now certain commands, like SetTargetDevices will perform much faster:

Serial

WARN  inputplumber::input::composite_device] Command SetTargetDevices took 220.566201ms

Parallel

DEBUG inputplumber::input::composite_device] Command SetTargetDevices took 7.258557ms
