Remove allocations_stubs

These were used to provide the `ts_record_*` functions regardless of
whether the `allocation-tracking` feature is enabled.  The allocation
tracking code is now implemented entirely in the `lib` crate, and only
when the feature is enabled, and so these stubs are no longer needed.
