Struct vs Interface Cast Benchmark

This benchmark measures performance of various alternatives to interface cast, which is expensive.
The reason is that interface cast involves "duct type check", and cast to type just checks a type hash value inside iface.

Cases:

• BenchmarkAssertStruct - Cast any to a concrete struct type (fastest).
• BenchmarkAssertIface - Cast to an interface.
• BenchmarkAssertWrapper - Cast to a concrete type and call a field that is an interface.
