Ethdebug isoltest framework

[nikola-matic]

Closes #16502.

Supports the following:

• EVM version
• optimizer on/off
• revert strings
• multi-source input
• compileViaSSACFG

Allows matching of specific portions of the output JSON, length checks on arrays, type checks. I could remove some of the current CLI tests, but would prefer to keep them in for the time being - most of the CLI tests requests outputs other than ethdebug, and the new EthdebugTest isoltest only supports reading of ethdebug data directly. In addition, there's no checks for errors like in syntax tests, which automatically disqualified migration of all of the 'invalid' CLI tests.

Some minor comments.

Mainly it would be good to have descriptions of the test format in the header so one doesn't have to go look through the code to find out what options there are.

Beyond that quite a few things can be const qualified I think. But that's more of a nit and not an official style guide... yet. :P

I applied all of the suggested changes, and went full const as well in preparation for the clang-tidy PR :D
The header descriptions are claude generated, and then cut manually to contain only the important bits.

You didn't fix the replace thing. Try defining the following test:

contract C {
    function f() public pure {}
}
// ----
// .compilation:
// {
//     "compiler": "<VERSION>"
// }

Simplified a bit since Json::type() exists :)

Sweet, TIL!
