[Fuchsia] Build Fuchsia profile runtime

Allow building the Fuchsia profile runtime in Chromium.
Add the runtime to the whitelist of files we tar up.
We need to have two cmake invocations because compiler-rt builtins CMake build avoid checks that need to link, but that's not the case for the Fuchsia profile runtime. Thus, when we build the profile runtime we need to have builtins already available.
