…d instead update typeOfValue and fix infinite loops

Summary:
With this we are now comparing a snapshot of the derivationCache with the new changes every time we are done recording the derivations happening in the HIR.

We have to do this after recording everything since we still do some mutations on the cache when recording mutations.



Test Plan:
Test the following in playground:
```
// @validateNoDerivedComputationsInEffects_exp

function Component({ value }) {
  const [checked, setChecked] = useState('');

  useEffect(() => {
    setChecked(value === '' ? [] : value.split(','));
  }, [value]);

  return (
    <div>{checked}</div>
  )
}
```

This no longer causes an infinite loop.

Added a test case in the next PR in the stack
…or for `no-deriving-state-in-effects`

Summary:
Revamped the derivationCache graph.

This fixes a bunch of bugs where sometimes we fail to track from which props/state we derived values from.

Also, it is more intuitive and allows us to easily implement a Data Flow Tree.

We can print this tree which gives insight on how the data is derived and should facilitate error resolution in complicated components

Test Plan:
Added a test case where we were failing to track derivations. Also updated the test cases with the new error containing the data flow tree
…he error instead of throwing

Summary:
TSIA

Simple change to log errors in Pipeline.ts instead of throwing in the validation

Test Plan:
updated snap tests
