Introduce the use of Chromium types (issue #1336).

- Move include/cef_build.h to include/base/cef_build.h.
- Move libcef_dll/cef_macros.h to include/base/cef_macros.h.
- Move include/cef_trace_event.h to include/base/cef_trace_event.h and include/internal/cef_trace_event_internal.h.
- Remove the "CEF_" prefix from TRACE macros.
- Add new include/base/cef_logging.h and include/internal/cef_logging_internal.h for logging support.
- Add new include/wrapper/cef_helpers.h for CEF_REQUIRE_*_THREAD macros and CefScopedArgArray.
- Delete the util.h headers used by tests that duplicated the above functionality.
