#36997 updated some asserts to be easier to read, however they are still repeated across different files.

We should enhance existing mobly asserts with some chip asserts for any custom typical operations like is_valid_.... checks for numbers/strings, validation of MEI values, validation of ranges and so on (e.g. https://github.com/project-chip/connectedhomeip/blob/master/src/python_testing/matter_testing_infrastructure/chip/testing/global_attribute_ids.py#L119 has some is_valid/standard/.... checks but as bools not as assets).

We should build an asserts module that builds upon mobly assertions to add matter specific ones somewhere in matter_testing_infrastructure and start using them (we could have something like matter_asserts.assert_valid_uint32(....) in the code.
