* Add suspendIfNeeded API and a global scope to track it Adds a "current" suspense config that gets applied to all updates scheduled during the current scope. I suspect we might want to add other types of configurations to the "batch" so I called it the "batch config". This works across renderers/roots but they won't actually necessarily go into the same batch. * Add the suspenseConfig to all updates created during this scope * Compute expiration time based on the timeout of the suspense config * Track if there was a processed suspenseConfig this render pass We'll use this info to suspend a commit for longer when necessary. * Mark suspended states that should be avoided as a separate flag This lets us track which renders we want to suspend for a short time vs a longer time if possible. * Suspend until the full expiration time if something asked to suspend * Reenable an old test that we can now repro again * Suspend the commit even if it is complete if there is a minimum delay This can be used to implement spinners that don't flicker if the data and rendering is really fast. * Default timeoutMs to low pri expiration if not provided This is a required argument in the type signature but people may not supply it and this is a user facing object. * Rename to withSuspenseConfig and drop the default config This allow opting out of suspending in some nested scope. A lot of time when you use this function you'll use it with high level helpers. Those helpers often want to accept some additional configuration for suspense and if it should suspend at all. The easiest way is to just have the api accept null or a suspense config and pass it through. However, then you have to remember that calling suspendIfNeeded has a default. It gets simpler by just saying tat you can pass the config. You can have your own default in user space. * Track the largest suspense config expiration separately This ensures that if we've scheduled lower pri work that doesn't have a suspenseConfig, we don't consider its expiration as the timeout. * Add basic tests for functionality using each update mechanism * Fix issue when newly created avoided boundary doesn't suspend with delay * Add test for loading indicator with minLoadingDurationMs option
