The useMemoCache polyfill doesn't have access to the fiber, and it simply uses state, which does not work with the existing devtools badge for the compiler. With this PR, devtools will look on the very first hook's state for the memo cache sentinel and display the Forget badge if present. The polyfill will add this sentinel to it's state (the cache array).

// This list should be kept updated to reflect additions to 'shared/ReactSymbols'.
|
|
// DevTools can't import symbols from 'shared/ReactSymbols' directly for two reasons:
|
|
// 1. DevTools requires symbols which may have been deleted in more recent versions (e.g. concurrent mode)
|
|
// 2. DevTools must support both Symbol and numeric forms of each symbol;
|
|
// Since e.g. standalone DevTools runs in a separate process, it can't rely on its own ES capabilities.
