encoding/xml: add Marshal doc about name conflicts
The docs for xml.Marshal state that the XML elements name is derived
from one of five locations in a specific order of precedence, but does
not mention that if the field is a struct type and has its name defined
in a tag and in the types XMLName field that an error will occur. This
is documented in the structFieldInfo function but not in the function
documentation, and the existing docs in Marshal are misleading without
this behavior being discussed.
Fixes #18564
