Ruslan Lesiutin a419575077 fix[devtools/useMemoCache]: add stub for useMemoCache in ReactDebugHook (#27472)
Currently, we have this error in our logs of the internal version of
React DevTools:
```
TypeError: Cannot read properties of undefined (reading 'memoCache')
    at Proxy.useMemoCache (chrome-extension://dnjnjgbfilfphmojnmhliehogmojhclc/build/react_devtools_backend_compact.js:151:71)
```

Looking at the build files of the extension, it fails here:
dddfe68820/packages/react-debug-tools/src/ReactDebugHooks.js (L333-L337)

Looks like `updateQueue` can be `undefined`, as it is not defined in
hook object here:
dddfe68820/packages/react-reconciler/src/ReactFiberHooks.js (L180-L186)

~~Also, it looks like `useMemoCache` implementation doesn't expect this,
so it should also result into TypeError here, line 1114:~~

dddfe68820/packages/react-reconciler/src/ReactFiberHooks.js (L1108-L1115)

~~Should this also be updated?~~

Harness for testing local changes to the react-devtools-inline and react-devtools-shared packages.

Development

This target should be run in parallel with the react-devtools-inline package. The first step then is to run that target following the instructions in the react-devtools-inline README's local development section.

The test harness can then be run as follows:

cd packages/react-devtools-shell

yarn start

Once you set both up, you can view the test harness with inlined devtools in browser at http://localhost:8080/
