[MatterYamlTests] null values that are saved are not substituted when… (

#29107)

* [MatterYamlTests] null values that are saved with saveAs are not substituted when the key used to saved them is used

* Update darwin-framework-tool tests codegen

* Add a new check in yaml_loader.py to ensure than the saveAs key is not the same as the attribute since this is a common mistake and it confuses the test suite that does not know if the attribute name should be replaced or not

* Update various YAML files such that they do not save the result of a read attribute with the exact same name than the attribute itself
