Add BR/EDR Scanning Capability to the Bumble

[akuker]

Currently the Bumble controller does not support Bluetooth "classic" (BR/EDR) scanning. It only has BLE scanning support.

This issue is to request that Bumble be updated to support Bluetooth classic scanning.

I'm still investigating the full impact of this, but at a minimum it will require adding the BR/EDR scanning HCI commands to the controller.

Note: I'm working on these updates myself. But, I wanted to put this ticket in to share what I'm doing and get feedback from the community (if any).

Note: Still working this issue. PR ETA in a week or two

Well this turned into a huge effort..... Current status: functionally tested, but working on cleaning up unit tests before I do a PR.
