457cc6a34f gn: Refactor build files to avoid build/secondary
In doing standalone bringup of Crashpad targeting Fuchsia, it seemed
tidy to keep the same literal paths to the dependencies that Chromium
needed and add stubs/forwarding to build/secondary in the Crashpad tree
as required to make those work.

However, when trying to build Crashpad in the Fuchsia tree itself, that
would require adding forwarding files to the Fuchsia tree to match the
Chromium directory structure, which would be awkward. Instead, have
explicit dependencies in the Crashpad tree that select the locations
for various dependencies.

Bug: crashpad:79, crashpad:196

2bb56fafe3 Rework GN files to start to support building standalone, and also in Chromium
- Adds a .gn and a build/BUILDCONFIG.gn that uses mini_chromium's
  build/BUILD.gn.
- Adds some stub BUILD.gn files in locations where Chromium expects them
  (in //build, //testing, //third_party) containing empty targets/configs.
  These are no-ops in standalone builds, but add functionality when
  building in Chromium.  This is in preference to having a global bool
  that conditionally does Chromium-y things in the Crashpad build files.
  These stub files are all contained in a secondary source root in
  build/chromium_compatibility, referred to by //.gn.
- Adds //base/BUILD.gn which forwards to mini_chromium/base. This is
  only used when building standalone so that both Chromium and Crashpad
  can refer to it as "//base".
- Changes references to other Crashpad targets to be relatively
  specified so that they work when the root of the project is //, and also
  when it's //third_party/crashpad/crashpad as it is in Chromium.
- Moves any error-causing Mac/Win-specific files into explicit if (is_mac)
  or if (is_win) blocks as part of removing the dependency on
  set_sources_assignment_filter().

As yet unresolved:
- CRASHPAD_IN_CHROMIUM needs to be removed when standalone; to be tackled
  in a follow up.
- Not sure what to do with zlib yet, the build file currently assumes
  "in Chromium" too, and similarly having Crashpad //third_party/zlib:zlib
  pointing at itself doesn't work.
