refactor(tvix/value): encapsulate attrset logic within value::attrs r/4454

The internal optimisations of the set representation were previously
leaking into the VM, which is highly undesirable.

Keeping it encapsulated allows us to do additional optimisations
within value::attrs without being concerned about its use in the VM.
