LE Manh Cuong 3db6d46a4e cmd/compile: add marker for skipping dowidth when tracing typecheck
The root cause of #33658 is that fmt.Printf does have side effects when
printing Type.

typefmt for TINTER will call Type.Fields to get all embedded fields and
methods. The thing is that type.Fields itself will call dowidth, which will
expand the embedded interface, make it non-embedded anymore.

To fix it, we add a marker while we are tracing, so dowidth can know and
return immediately without doing anything.

Fixes #33658
