This introduces the initial support for Bluetooth 5.2 features:
* ISO channels:
+ tools/isotest command line tool to run validation tests
* L2CAP Enhanced Credit Based Flow Control Mode
+ tools/l2test has been update to include the new mode
* Enhanced ATT Bearer:
+ Client and Server support
+ Include all new procedures
+ Automaticlly detects and enables channels
+ Number of channels configurable via main.conf
* Monitor:
+ HCI/LL Bluetooth 5.2 command/event decoding
+ ISO packets decoding
+ L2CAP Enhanced Credit Based Flow Control Mode decoding
+ Enhanced ATT packets decoding
* Emulator:
+ CIS/Unicast emulation support
- BIS/Broadcast emulation not yet supported
