APIs for BLE address generation

In BLE there are 4 types of addresses:
- Public
- Random static
- Random resolvable private address
- Random non-resolvable private address

According to the specification v4.2 Vol 6 Part B Section 1.3 each of these addresses has a specific format. It would be desirable to have APIs that can generate these addresses automatically so that the user does not have to worry about the details of valid device address generation.

Start by reading the BLE specification v4.2, Vol 6 Part B Section 1.3, which defines the four address formats named in the issue. Then inspect the repository's existing controller abstraction and public API conventions. Done means agreeing on and implementing APIs that generate valid public, random static, resolvable private, and non-resolvable private addresses.
