Bluetooth: Disable "IsConnectable" property for ChromeOS implementation.

The IsConnectable property tells if a given device can be re-connected
later once paired. If it is false, the device is not supposed to respond
to a connection attempt from the host, and since we know it, we don't
show the connect button for this kind of devices.

This fix rollbacks the IsConnectable implementation in ChromeOS and
default its value to true because some mice don't support pairing and should be possible to connect to them regardless the value of this property.

BUG=chromium:220553
TEST=Pair to Microsoft mouse 5000, disconnect and try to connect again.
