 Build/Test Tools: Fix React Refresh hot reloading for block plugins.

 The `react-refresh-entry.js` script was bundling its own copy of
 `react-refresh/runtime` instead of using the `window.ReactRefreshRuntime`
 global set up by `react-refresh-runtime.js`. This created two separate
 runtime instances: the entry script set up hooks on its bundled copy,
 while
 plugins called `performReactRefresh()` on the window global — a different
 instance with no hooks registered.

 This splits the development webpack config into two configs so that
 `externals` only applies to the entry script. The runtime config bundles
 `react-refresh/runtime` and exposes it as `window.ReactRefreshRuntime`,
 while the entry config uses that global as an external.

 Props manzoorwanijk, wildworks.
