Description

I did some size profiling on our current binary based on v8.0.0 tracking unstable using
bloaty. I also was able to get visualisation of the binary components. looks like the ef_tests is making it's way into the binary which is kinda not necessary imo. Removing it would effectively reduce the binary size by ~8mb, which is about 10% reduction in the current binary size. and the web3signer_tests as well if not need.

thanks to https://github.com/ahaoboy/bloaty-metafile I was able to convert the bloat json to get an output to visualise on https://esbuild.github.io/analyze/
