    nimble/ll: Add macros to handle conn handles
    
    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.
