Create extensions_test_support build target

* Create extensions/common/test_util.h for shared test code
* Consolidate duplicated CreateExtensionWithID() functions
* Create extensions_test_support build target because you can't have multiple
  files named test_util.h in a single build target on MSVS, all the other
  names are taken (test_utils.h, extension_test_util.h, etc.), and this gets
  us a step closer to having an extensions-only test suite.
* Fix some missing dependencies for the extensions_common target
* Remove unnecessary includes that create a dependency on themes
