CI: Remove additional Qt PDBs

We avoid shipping the Qt binary tool PDBs because we haven't had a need
for them.

Qt 6.5 added the tracepointgen tool. Let's exclude that.

Somewhere between Qt 6.5.3 and 6.6.1, the syncqt tool started building
PDBs even in Release configuration. Let's just exclude it for now. We
can unravel that mystery another day.
