This adds optional multi-architecture builds, allowing to compile x86 and x64 in one build. The correctness fuzzer can be configured to compare the two executables, e.g. to compare x86 to x64 run the launcher with: --second-d8=clang_x86/d8 in an x64 build. Configuring the executable's architecture is now simplified and inferred from the gn build configuration. Building for clusterfuzz has now a new canonical target that can be used by the infrastructure (defaults to d8). The clusterfuzz release builder is now defined to compile multi-arch builds, which will have an effect as soon as the infrastructure refers to the new clusterfuzz target.
