fix(interpreter): avoid overflow when checking if mem limit reached

[grandizzy]

I hit this panic while doing intensive tests with foundry

Message:  attempt to add with overflow
Location: /home/george/.cargo/registry/src/index.crates.io-6f17d22bba15001f/revm-interpreter-4.0.0/src/interpreter/shared_memory.rs:98

This is a bug. Consider reporting it at https://github.com/foundry-rs/foundry

Proposed fix is to use saturating add to check if limit reached
