Rename noopCheck to identityFunctionCheck

[aryaemami59]

What is the new or updated feature that you are suggesting?

Rename noopCheck to identityFunctionCheck

Why should this feature be included?

• To provide a more accurate description since a no-op function is more like () => {}, an identity function is like x => x.
• It would also be more consistent with the definitions defined in Reselect.

What docs changes are needed to explain this?

The No-op selector check section will have to be slightly tweaked.

adding the 9.0 milestone as this would be a breaking change :)

I personally don't have any objections to the change though - we'd have to add it to the migration guide, but I suspect the amount of people impacted would be low
