Fix: Avoid Infinite Recursion in on_eval Method

[voronor]

Summary:

This pull request addresses an issue where the on_eval method in the EvalTracer trait was calling itself recursively, resulting in infinite recursion. Specifically, the following line:

EvalTracer::<H>::on_eval(self, machine, handle, opcode, position)

was causing the method to call itself indefinitely, which is incorrect and leads to a runtime stack overflow.

Fix:

To fix this issue, we updated the code to call the on_eval method directly on self, since self is the concrete type that implements the EvalTracer trait. The corrected code looks as follows:

impl<'config, H, T: EvalTracer<H>> crate::EvalTracer<State<'config>, H> for T {
	fn on_eval(&mut self, machine: &Machine, handle: &H, opcode: Opcode, position: usize) {
		// Correctly delegate the call to `on_eval` on the concrete implementation of `self`.
		self.on_eval(machine, handle, opcode, position)
	}
}

Importance:

This fix is critical because the original code could have led to infinite recursion, resulting in a stack overflow and potential application crashes. By fixing the recursion and ensuring that the on_eval method is called properly, we improve the stability and reliability of the code.

The PR itself at most does nothing and reduce clarity.
