1661930 - Include TI flag in bytecode cache MIME type

Status: RESOLVED FIXED

Bug 1661426 part 1 added a TI flag to XDR but that was not sufficient: after flipping the Warp browser pref without updating the build, the bytecode cache can get confused and websites don't load correctly.

I have a patch to add a separate XDR build id. We can then use that in both places.

This lets us include some extra flags in the MIME type that's used by the bytecode
cache. It also simplifies the XDR code a bit.

The approach is similar to Wasm's GetOptimizedEncodingBuildId.
