nimble/ll: Add macros to handle conn handles

Browse Source 
Connection handles for ACL, CIS and BIS are assigned from the same pool
so we'll just split that poll into separate ranges - we'll use msbyte as
an indicator for type of conn_handle, this gives us 256 handles of each
type which should be more than enough.
