Drop a couple of unused files that broke certain jumbo builds.

A completely unused object file in a static library will be
ignored by the linker, but with jumbo builds unused cc files will
be grouped with used cc files and the object file will no longer
be ignored.

If the cc file contains code that is bad it can then trigger followup
linker errors which happened in this case where debug component
windows builds had too many constructors and destructors for
WebAssociatedURLLoader when building webkit_unit_tests.exe
