FindDoxygen: Use a stable reference to the location of global resources

FindDoxygen generates some files based on the version of Doxygen whose
content will not vary across a project and are therefore a global
resource that can be shared by all calls to `find_package(Doxygen)` and
to `doxygen_add_docs`.  We currently use `${PROJECT_BINARY_DIR}` to
reference their location, but this is not stable because `project()`
calls in a subdirectory can change it.  Use `${CMAKE_BINARY_DIR}`
instead.
