audiopolicy: increase binder command timeout for some commmands

Extend timeout for SET_DEVICE_CONNECTION_STATE and HANDLE_DEVICE_CONFIG_CHANGE
binder commmands in IAudioPolicyService.cpp while we investigate why BT A2DP
device connection/disconnection can sometimes take more than 5 seconds.

Bug: 74840091
Test: check that no timout occurs for A2DP headset connections
