Fix install header paths, add SignedPtr.h

Here's another attempt, incorporating
<https://bugs.webkit.org/show_bug.cgi?id=236471> and
<https://bugs.webkit.org/show_bug.cgi?id=236466>, which were also reverted.

The major new insight is that during `install` builds, the Copy Files phases
need to copy to an absolute path, not "Relative to Build Products". To do that,
they need to be based off a separate path variable than the main Headers phase,
so that they still copy relative to build products during engineering builds.
