Add option to skip `invalidate` when using `icache.set` or `icache.getOrSet`

Enhancement

There are currently two cache middlewares available, standard cache and icache (invalidating cache) and it can be cumbersome to have to use both for scenarios when a value needs to stored across renders but when set not cause an invalidation. Additionally the typing is much better on the icache compared to the basic typing available with the cache

For the .set and .getOrSet APIs, add a third optional parameter to determine if the operation should cause an invalidation. The default behaviour would remain the same, i.e. cause an invalidation.
