roll: pigweed pw_bluetooth: Fix RFCOMM information length off by one

A misreading of the spec led to confusion on whether credits was counted
as part of information_length. It is _not_, but it is included in the
calculation for max allowed payload.

Fix this and standardize on `information` as the name used in the spec
vs payload.

Also add helper flag for checking whether a frame is UIH or not

Add standalone unit tests for RFCOMM.
