`act` checks the environment to determine whether to fire a warning. We're changing how this check works in React 18. As a first step, this refactors the logic into a single function. No behavior changes yet.

If `IS_REACT_ACT_ENVIRONMENT` is set to `false`, we will suppress any `act` warnings. Otherwise, the behavior of `act` is the same as in React 17: if `jest` is defined, it warns. In concurrent mode, the plan is to remove the `jest` check and only warn if `IS_REACT_ACT_ENVIRONMENT` is true. I have not implemented that part yet.

This adds support for disabling spurious
actwarnings using a global. The tentative name isIS_REACT_ACT_ENVIRONMENT, though that may change before release.If
IS_REACT_ACT_ENVIRONMENTis set tofalse, we will suppress anyactwarnings. Otherwise, the behavior ofactis the same as in React 17: ifjestis defined, it warns.In concurrent roots, the plan is to remove the
jestcheck and only warn ifIS_REACT_ACT_ENVIRONMENTis true. I have not implemented that part yet.
