refactors interpreter_exec.jl further

This commit refines `interpreter_exec.jl` further, on top of #53218.
In detail, by using `Base.Experimental.@compiler_options compile=min`,
it's now possible to mimic the effect of `julia --compile=[min|yes]`.
This commit is leveraging it and includes `interpreter_exec.jl` from
`test/compiler/ssair.jl`, allowing us to get better stack traces and
test summaries.

In addition, I've introduced several tests concerning the `src.inferred`
values and have relocated the tests from #47066 within
`interpreter_exec.jl` to `test/compiler/irpasses.jl`, since it is
related to Julia-level compilation and not to interpreter execution.
