Use Qt CMake APIs to exclude files from Unity Build

This is a bit of a cleanup, mainly around unity build, and a few other minor things: - I replaced the direct inclusion of sources files using `set_source_files_properties`, and instead used `NO_UNITY_BUILD_SOURCES` when possible. In most cases, they are being excluded in their respective `qt_internal_extend_target` but sometimes I had to make a new extension. - In few cases, we had to manually exclude the NO_PCH files, so, I instead passed them directly to the NO_PCH_SOURCES which also exclude them from the unity build as well. - Removed a few unnecessary "" Pick-to: 6.5 Task-number: QTBUG-109394 Change-Id: I466576592c1d115a2da4d88672c1e4b9f995f2ed Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>
