This is fairly straightforward to represent as a GENERATED_FILES, though
we have to take some care to construct the outputs tuple correctly. This
script needs to run during export, and unfortunately none of the STL
headers have proper file extensions, so the 'new' header is
special-cased in the recursive make backend to serve as a marker for
running it in the correct tier.
We can't remove the stl-headers file yet because it is still used for
the system header generation.

Since the introduction of the STL wrappers, they have included
mozalloc.h, and multiple times, we've hit header reentrancy problems,
and worked around them as best as we could.
Taking a step back, all mozalloc.h does is:
- declare moz_* allocator functions.
- define inline implementations of various operator new/delete variants.
The first only requires the functions to be declared before they are used,
so mozalloc.h only needs to be included before anything that would use
those functions.
The second doesn't actually require a specific order, as long as the
declaration for those functions comes before their use, and they are
either declared in <new> or implicitly by the C++ compiler.
So all in all, it doesn't matter that mozalloc.h is included before the
wrapped STL headers. What matters is that it's included when STL headers
are included. So arrange things such that mozalloc.h is included after
the first wrapped STL header is fully preprocessed (and all its includes
have been included).
