Add traces to the Bluetooth Security Manager and Privacy controller.
The traces are made to be comprehensive to improve the ux when users submit bugs.
A centralized set of helpers has been created to convert BLE types to string.
* BLE: Add SM traces
* BLE: Add traces to Security Manager PAL
* BLE: Make SM traces consistent.
- Prefix with Connection <id> - when appropriate.
- Display parameters after `:`.
- If multiple parameters should be displayed name then and print the value after =. They are separated by a `,`.
* BLE: Fix SM random number generation.
Only the first 8 bytes were generated from the stack.
* BLE: Regenerate CSRK if it is all zeroes.
* BLE: Add trace into privacy modules
Address resolution is set at the debug level as it is a very common operation and may clutter the output.
* Address trace review for SM:
- Put privacy traces in BLPR
- Add missing traces in PALSecurityManagerImpl.cpp
- Add missing EventHandler null pointer check
- Typo and parameters order fix.
