Include dependencies for clang-tidy and header-abi-dumper

We've been getting these dependencies transitively through the
dependency on the object itself (which is a workaround for the lack of
dep file support in these tools). But for remote builds to work, we need
to know about these dependencies like any other object compilation.

For regular builds, this increases the size of the ninja file by a few
tens of megabytes (~1-2%).

WITH_TIDY builds were already larger (~40-50%), but are now about 90%
larger than a normal build.
