chore: add single versioned implementation of act for DevTools tests (#28186)

- Moving `act` implementation to a single getter-function, which is
based on React version we are testing RDT against.
- Removing unused mocks for `act`, which were designed for legacy
versions of React, validated with running tests against React 16 build.

DiffTrain build for commit https://github.com/facebook/react/commit/9a1db2d21fac88a42094fa3fc266d1692551a5bd.
