bluez5/backend-native: Add HFP/HSP hardware offload datapath configuration

Browse source 
Add support for configuring the SCO hardware offload data path for
HFP/HSP profiles using the Bluetooth SIG-specified procedure. This
enables vendor-specific SCO offload integrations.

Changes:
- Add `bluez5.hw-offload-datapath` configuration property (default: 0)
- Implement `sco_offload_btcodec()` to set BT_CODEC socket option
- Add `SPA_BT_FEATURE_HW_OFFLOAD` quirk feature flag
- Apply offload configuration when creating SCO sockets if quirk enabled
- Document new property in pipewire-props.7.md

The datapath ID is configurable via device parameters and only applied
when the hardware offload feature flag is set in quirks, allowing
platform-specific SCO offload implementations.
