[LE Audio] New logic to generate the QR code
Currently the QR code string is generated in SettingsLib, and use
"<" and ">" to format the string.
Because the formatted string are multi layer nested, like
A:<B:<C:<<>;D:<>>;>;E:<F:<B:>;>;>;
Using Regex cannot handle this case,
- Regex cannot tell which B: is label for filed, which B: is user input
- Regex cannot tell which pair of <> is the correct open and close for B
- And these is no easy fix
The BluetoothLeBroadcastMetadata already implements the Parcelable
interface, use Parcel to serialize the string to fix issues.
Also, add unit test.
Fix: 248409874
Test: Unit test
