This set ensures events received have the minimum required length using
skb_pull to advance on packet, it also rework some of events to take
advantage flex_array_size for events that can have variable size.

This should fix issues found by szybot like:

[syzbot] KMSAN: uninit-value in hci_event_packet

v2: Fixes issues found by CI
