Options: Add new alloptions and pre_cache_alloptions filters.

Browse Source 
`pre_cache_alloptions` is run before the alloptions array is inserted into the cache, and is valuable for sanity checking the options, particularly if your caching scheme has size limitations.

`alloptions` is run before returning the alloptions array, and is useful for when you have extra information that alloptions should return.

Props sebastian.pisula, keesiemeijer.
Fixes #33958.
