StorageId branded type and validator

It would be cool if StorageId were a branded type (like Id) rather than just a type alias, and it would also be cool if there were a validator for storage IDs (e.g. v.storageId()).

You're prescient, work with this as a side effect is underway

This was done in a previous release, for anyone following up. I also realized this just works:

defineSchema({
  table: defineTable({
    field: v.string() as Validator<MyStringType>
  })
)}

defineSchema({
  table: defineTable({
    field: v.string() as Validator<MyStringType>
  })
)}

field will be typed as MyStringType and give you errors on functions like withIndex, and give you that type on returned documents.

To clarify, we now have Id<"_storage"> which can be used in place of storage IDs. Similarly v.id("_storage") works.
