Execute compilation benchmarks on CI

[xermicus]

We need a CI workflow which benchmark the compilation time and memory consumption of the compiler on our reference bench-marking hardware.

Note that currently there are no such benchmarks implemented. So the issue has two tasks:

• Implement such benchmarks.
• Implement a CI workflow executing them.

I'd like to have this workflow executed after all other jobs finished and post the benchmark results (diffed against master) as a PR comment.

A follow up issue will be to create more benchmarks that focus on more realistic examples from our overarching EVM test suite.
