feat: add comptime support for modulus_* compiler builtins

Description

Resolves

Summary*

This PR changes the function std::compat::is_bn254 to run in a comptime context. To do this I've had to implement a few compiler builtins within the interpreter.

I've had to mangle std::compat::is_bn254 a bit to get around restrictions on when a function can be called in a comptime context however.

This works around around the loop unrolling issue experienced in #4535.
