GD metrics: Add shim layers for metrics in GD

1) Add shim layer for MetricIdManager
2) Add shim layer for metric logging functions who take metric id
3) reference the 2 shim layers at btif/, main/shim and stack/

Bug: 181819141
Test: atest bluetooth_test_gd
Manual test by printing log at legacy stack and gd stack to make sure
function calls, parameters and callbacks are fowarded correctly
