Converts AdjustNumericScale to #[sqlfunc]. It carries the target NumericMaxScale, so the function takes &self and builds its output type in an output_type_expr. sqlname keeps the SQL name adjust_numeric_scale.

The registry reports only the macro provenance fields moving, on the one record. No declared property changed.

Based on #39086.

`AdjustNumericScale` carries the target `NumericMaxScale`, so the annotated
function takes a `&self` receiver and the macro generates `call` as a method on
the existing struct instead of defining a unit struct. The hand-written
`Display` wrote the fixed string `adjust_numeric_scale` without reading the
payload, so `sqlname` reproduces it and the impl is deleted. The macro then
generates `FuncName` with `NAME` from the annotated function's name, which is
the `"adjust_numeric_scale"` the manual `func_name!` entry declared, so that
entry is deleted to avoid a duplicate impl.

The deleted `EagerUnaryFunc` impl overrode only two methods:

* `call`: the annotated function's body, unchanged.
* `output_sql_type`: expressed as `output_type_expr`, which reads `self.0` and
  the `input_type` binding. The generated tail ORs in `propagates_nulls &&
  input_type.nullable`, and `propagates_nulls` derives to `true` from the
  non-nullable `Numeric` input, so the result is the same
  `nullable(input_type.nullable)` the deleted body returned.

`introduces_nulls` is not overridden: `Result<Numeric, EvalError>` derives
`false`, which is what the impl inherited. `could_error`, `propagates_nulls`,
`preserves_uniqueness`, `inverse` and `is_monotone` were not overridden and keep
deriving as before.

The registry reports only `sqlfunc_signature` moving, on the single
`adjust_numeric_scale` record. No declared property changed.

Folded into #39062, which now carries all twenty file conversions as separate commits, per review feedback to land them as one PR.
