  battery: Add component battery objects

Allow one Bluetooth device to export multiple Battery1 objects while
keeping the legacy aggregate object at the device path.

Component objects expose their parent Device1 path, a stable identifier,
an optional percentage, and an optional charging state. Extend
BatteryProvider1 handling with the same semantics so external providers can
publish multiple batteries too.

Keep component objects and their new properties behind the experimental
D-Bus flag while the API is being established.

  doc: Document component battery objects

Describe the experimental component Battery1 properties, their opaque
object paths, and how BatteryProvider1 implementations publish several
batteries for one device.

  fastpair: Add Message Stream battery profile

Connect to the experimental Fast Pair Message Stream service advertised by
compatible BR/EDR devices and parse its 16-bit-length framed messages.

Publish left, right, and case values as component Battery1 objects.
Include unknown percentage and charging-state transitions. Decode unknown
levels using the generic Battery Notification status bit while treating
the TWS-specific case value 0xff as unavailable.

If only the Message Stream is lost, invalidate its values and reconnect.
Use exponential backoff and reset it only after a battery-producing stream
remains stable. Remove the objects once the BR/EDR bearer disappears.

Keep pending connection callbacks alive through cancellation and ignore
callbacks for detached or superseded channels.

  test: Add Fast Pair Message Stream tool

Add a standalone profile client that prints Fast Pair Message Stream frames
and can optionally publish left, right, and case values through
BatteryProvider1.

Publish dynamic component lifecycle signals, scope providers per adapter,
and invalidate measurements when a stream closes. Warn users to disable the
built-in Fast Pair plugin when using the external profile.
