extmod/btstack: Include value handle in client read/write events.

Browse Source 
This replaces the previous pending operation queue (that used to also be
shared with pending server notify/indicate ops) with a single pending
operation per connection. This allows the value handle to be correctly
passed to the Python-level events.

Also re-structure GATT client event handling to simplify the packet handler
functions.
