checks: centralize printing of property names in failure messages

Some failure messages apply to a specific property. Add a FAIL_PROP()
macro for failure messages which are specific to a property. With that,
failure messages can print the property name in a standard way. Once
source line numbers are supported, then the file and line number of the
property can be used instead of the node file and line number.

Convert the existing messages related to properties to use the FAIL_PROP
macro and reword the messages as necessary.
