Fix LEA hearing aid not shown in hearing device page after reboot issue

Only ASHA hearing aids' info is updated after reboot. This causes the LE
audio hearing aids are not correctly shown when entering a11y hearing
devices page due to the lack of hearing aid info.

We should call `CachedBluetoothDeviceManager.updateHearingAidsDevices()`
when hearing aid related services are connected, which includes
HearingAidProfile, LeAudioProfile and HapClientProfile.
