Re: [I] update data type equality in code base to use semantic_equality in `arrow-rs/arrow-schema` instead [datafusion]

   Still blocked on apache/arrow-rs#10902 and an arrow 60 release, so I am holding the assignment rather than freeing it up.
   
   @Rich-T-kid also worth flagging that `EquivalenceGauge` only relaxes field name, nullability and metadata, so it cannot express the decimal precision/scale and timestamp unit/timezone cases in `DFSchema::datatype_is_semantically_equal`, nor `Dictionary<K,V>` == `V` or `Utf8`/`Utf8View` in `datatype_is_logically_equal`. Reads like a partial extraction rather than a full swap.
