    This is a reland of 40d66d8b
    
    The fix disambiguates duplicate symbols in the generated embedded
    builtins file.
    
    Original change's description:
    > [build] Make separate snapshot for trusted variant
    >
    > This enables side-by-side snapshots with and without untrusted-code
    > mitigations. It'll be the default in all V8 stand-alone builds
    > with external startup data. Internal snapshots are not supported.
    >
    > The files snapshot_blob.bin and snapshot_blob_trusted.bin will be
    > bundled with V8 on swarming and the correct file is loaded dependent
    > on the --untrusted-code-mitigations runtime flag.
    >
    > Likewise we embed two snapshots for builtins.
    >
    > Side-by-side snapshots won't be supported in Chromium.
