shared: Add bcs_procedure_data aggregation and procedure data API
Define bcs_procedure_data to hold per-procedure CS results from both
the local initiator and remote reflector, including subevent step data,
selected TX powers, procedure enable config, CS config, sw_time values,
and BLE connection interval.
Add cs_proc_state with a 16-entry ring buffer in cstracker to track
procedures keyed by procedure counter, accumulating results
independently from each side until both report all-results-complete.
Update parse_mode_{0,1,2,3}, parse_step, and parse_subevent_steps with
output pointer parameters to capture remote reflector step data.
Introduce parse_cs_local_initiator_data() to store local HCI subevent
results, handling both initial and continuation events. Update
parse_ras_data_segments() to route decoded RAS subevent data into the
matching cs_proc_state as reflector results.
Add bt_rap_set_procedure_data_cb() to register a callback fired once
both local and remote results are complete for a given procedure.
Add bt_rap_set_local_sw_time(), bt_rap_set_remote_sw_time(), and
bt_rap_set_conn_interval() so callers such as rap_hci.c can supply the
CS capability sw_time and connection interval required by upper-layer
distance calculation algorithms.
Remove unwanted function rap_detached , fix for rap profile level
disconnections

profiles/ranging: Emit CS ProcedureData signal over D-Bus
Serialize completed BCS procedure data (subevent/step results,
CS config, and procedure-enable parameters) into a byte blob and
emit it via a new ProcedureData D-Bus signal on the CS interface,
so an external ranging estimation daemon can consume raw controller
measurements

doc: Update ProcedureData signal doc for byte-blob format
Document the create_context CS configuration parameter added
alongside the CS Create Config command.
Update the ProcedureData signal signature from dict to array{byte},
matching the byte-blob serialization now used in rap.c, and drop
the per-field dict documentation (procedureCounter, subevent
results, csConfigParam, etc.) that no longer applies since the
signal now carries an opaque binary blob instead of a structured
dict.

Add support for discovering and reading HIDS 1.1 SCI (Subrated
Connection Interval) characteristics:
- HID SCI Mode (0x2c39)

When the HID Information flags indicate SCI is supported (bit 2),
the SCI Mode and SCI Information characteristics are read after
the HID Information is obtained.

mgmt: Add Shorter Connection Interval setting and Load Connection Subrate
Add the Shorter Connection Interval setting bit (25) to indicate
controller support for SCI feature.
Add the Load Connection Subrate command (0x005C) which allows
loading connection subrate parameters for devices that support
shorter connection intervals as defined in Bluetooth 6.2.

Implement load_conn_subrate() to load per-device connection subrate
parameters via the new MGMT_OP_LOAD_CONN_SUBRATE command. Parameters
are read from the [ConnectionSubrate] section of device info files
and sent to the kernel when the SCI setting is supported.
The subrate parameters include connection interval range, subrate
factor range, max latency, continuation number, and supervision
timeout as defined in the Bluetooth 6.2 SCI feature.

Add Load Connection Subrate test cases using the recommended
connection subrate parameters from the HOGP v1.2 specification for
each of the four HID modes:
- Fast: interval 1.25-5 ms, latency 0, subrate 1-4, cont_num 3
- Default: interval 7.5-15 ms, latency 0, subrate 1-4, cont_num 0
- Low Power: interval 7.5-15 ms, latency 100, subrate 1-4, cont_num 0
- Full Range: interval 1.25-15 ms, latency 0, subrate 1-4, cont_num 1
Supervision timeouts are computed as (1 + Peripheral Latency) *
Subrate Max * Connection Interval Max * 2 per the spec.

l2cap-tester: Add SCI mode tests for LE client connections
Add L2CAP LE client connection tests that load Connection Subrate
parameters (via MGMT_OP_LOAD_CONN_SUBRATE) before establishing the
connection, using the HOGP v1.2 recommended values for each of the
four HID SCI modes:
- Fast: interval 1.25-5 ms, latency 0, subrate 1-4, cont_num 3
- Default: interval 7.5-15 ms, latency 0, subrate 1-4, cont_num 0
- Low Power: interval 7.5-15 ms, latency 100, subrate 1-4, cont_num 0
- Full Range: interval 1.25-15 ms, latency 0, subrate 1-4, cont_num 1
Add the test_l2cap_le_62 macro (HCIEMU_TYPE_BREDRLE62) since SCI
requires a 6.2 controller. The subrate parameters are loaded with
the client's runtime bdaddr during setup_powered_client before the
outgoing LE connection is initiated.
