input/hog-lib: Add discovery support for HIDS 1.1 SCI attributes
Add support for discovering and reading HIDS 1.1 SCI (Subrated
Connection Interval) characteristics:
- HID SCI Mode (0x2c39)
- HID SCI Information (0x2c3a)
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.

mgmt-tester: Add tests for SCI setting and Load Connection Subrate
Add HCIEMU_TYPE_BREDRLE62 device type for testing Bluetooth 6.2
features and add test cases:
- Set Low Energy on 6.2 - SCI Setting: verifies that the SCI
setting bit (25) is reported in supported/current settings
for a 6.2 controller.
- Load Connection Subrate - Invalid Params 1: verifies invalid
parameters are rejected.
- Load Connection Subrate - Success 1: verifies loading valid
connection subrate parameters succeeds.

adapter: Add support for loading connection subrate parameters
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.

mgmt-tester: Add HIDS recommended SCI parameter tests
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.

emulator/bthost: Add LE Connection Rate Request support
Add bthost_le_conn_rate() to send the LE Connection Rate Request
(0x20a1) command for a given connection handle.
Also handle the LE Connection Rate Change event (0x37).
This allows testing a peripheral (server) handling of the Shorter
Connection Interval feature by having the emulated central initiate
the connection rate request on connect.

side of the Shorter Connection Interval feature. The emulated client
(central) is configured via bthost_le_conn_rate() to send an LE
Connection Rate Request once connected, using the HOGP v1.2
recommended values for each of the four HID SCI modes (Fast, Default,
Low Power, Full Range).
