[jit] Implement ScriptProfile to collect instruction profiles. (#57397) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/57397 Introduces two main classes in C++ runtime: ScriptProfile is the implementation for enalbing and disabling interpreter profiling in C++. This should be only used from Python, and we will add corresponding Python API in the next diff. InstructionSpan is a utility class to instrument execution of each single instruction. A start timestamp is recorded in the consturctor, and an end timestamp is recorded in the destructor. During destruction, this will send runtime data to all enabled ScriptProfile instances.
