Put the hrtime backing store in the process methods binding data so that it can be integrated into the snapshot builder. For now we simply discard the contents of the hrtime buffer during serialization and create new buffers upon deserialization because the contents are only useful in a synchronous call. This also moves the helper function for creating V8 FastAPI methods into `Environment::SetFastMethod()` for code reuse. The v8::CFunction need to be created before the Environment is created so that we have the CTypeInfo address available for external reference registration.

The tests are modeled after another patch that includes v8::CFunctions into Node.js's builtin snapshot.

Put the hrtime backing store in the process methods binding data so that it can be integrated into the snapshot builder. For now we simply discard the contents of the hrtime buffer during serialization and create new buffers upon deserialization because the contents are only useful in a synchronous call. This also moves the helper function for creating V8 FastAPI methods into `Environment::SetFastMethod()` for code reuse. The v8::CFunction need to be created before the Environment is created so that we have the CTypeInfo address available for external reference registration.

Put the hrtime backing store in the process methods binding data
so that it can be integrated into the snapshot builder. For
now we simply discard the contents of the hrtime buffer during
serialization and create new buffers upon deserialization because
the contents are only useful in a synchronous call.
This also moves the helper function for creating V8 FastAPI methods
into
Environment::SetFastMethod()for code reuse. The v8::CFunctionneed to be created before the Environment is created so that we
have the CTypeInfo address available for external reference
registration.
