Scan LE audio hearing aids in HearingDevicePairingDetail 

Only ASHA hearing aids can be scanned from HearingDevicePairingDetail.
Add the ability to scan LE audio hearing aids (which supports HAP
profile) in hearing device page.

Since we're not sure what will hearing aids vendors organize the data in
the advertisement packet, add the filters as long as it's possible to
increase coverage when scanning hearing aid devices.
