Ensure `rs-matter` transactions/exchanges conform to the data consistency and atomicity of the Matter Spec

[ivmarkov]

At the moment rs-matter has NO atomicity (exchanges failing in the middle leave the state of the device with partial modifications)
... and has NO data consistency (partial writes from an on-going write-attribues / invoke operations are visible by readers who report attribute reads).

But the question is what the Matter Spec mandates. Which is unclear. See
project-chip/connectedhomeip#40713

Andrey, sorry to bother. Do you think you could shed some light on this issue?
(Not sure when the other Matter folks would react on project-chip/connectedhomeip#40713 inside the chip repo itself.)
