[PATCH BlueZ v3 0/3] Add CS procedure data aggregation and D-Bus export

This series adds support for collecting, aggregating, and exporting
Channel Sounding procedure data to userspace.

The first patch introduces a new procedure-data aggregation layer in
shared/rap. It tracks local initiator and remote reflector results for
each procedure, combines them once both sides are complete, and provides
a callback-based API for consumers.

The second patch builds on this infrastructure by serializing completed
CS procedure data into a binary blob and exposing it through a new
ProcedureData signal on the CS D-Bus interface. This allows external
ranging estimation daemons to consume raw controller measurement data
without requiring BlueZ to expose or maintain a fixed D-Bus structure
for evolving CS result formats.

The final patch updates the D-Bus API documentation to reflect the new
signal format

Changes in v3:
- Rebase the changes

Naga Bhavani Akella (3):
