Use DX names (acrn:title) instead of element names in messages.
Add missing message in rdt_support.xsd (all asserts need an annotation
with documentation for the error message that will be reported).

Now we have transitioned to use XML schema to record all data validation
rules against board and scenario XMLs. While most checks originally in the
Python scripts are about the syntax of the XML files and thus naturally
covered by the XML schemas, there are still a few that conduct cross-check
on data consistency.
This patch migrates those checks into XML schema as assertions.
