[Rust] Fix a couple of oversights in the API

1. Some SSA-specific functions are now implemented on
   `LowLevelILFunction<M, SSA>` rather than `Ref<LowLevelILFunction<M, SSA>>`.
2. A lifting helper for `LLIL_TAILCALL` is added to `LowLevelILFunction`.
3. `PossibleValueSet::ImportedAddressValue` now holds the value.
