fix(core): ngOnDestroy on multi providers called with incorrect context (#35840)
Currently destroy hooks are stored in memory as `[1, hook, 5, hook]` where the numbers represent the index at which to find the context and `hook` is the function to be invoked. This breaks down for `multi` providers, because the value at the index will be an array of providers, resulting in the hook being invoked with an array of all the multi provider values, rather than the provider that was destroyed. In ViewEngine `ngOnDestroy` wasn't being called for `multi` providers at all. These changes fix the issue by changing the structure of the destroy hooks to `[1, hook, 5, [0, hook, 3, hook]]` where the indexes inside the inner array point to the provider inside of the multi provider array. Note that this is slightly different from the original design which called for the structure to be `[1, hook, 5, [hook, hook]`, because in the process of implementing it, I realized that we wouldn't get passing the correct context if only some of the `multi` providers have `ngOnDestroy` and others don't. I've run the newly-added `view_destroy_hooks` benchmark against these changes and compared it to master. The difference seems to be insignificant (between 1% and 2% slower). Fixes #35231. PR Close #35840
