pw_bluetooth: Update comments in HCI event defs

Update HCI event definitions (from 7.7 "Events") to include:
- A core spec section reference
- The HCI event name itself (e.g., "HCI_Inquiry_Complete")
- Some events we haven't implemented (as TODOs)

Bug: b/265052417
Test: No pigweed regressions, all Sapphire bt-host tests pass.
