GH-35828: [Go] Add `array.WithUnorderedMapKeys` option for `array.ApproxEqual` (#35823)

### Rationale for this change

If we store the value of the `*array.Map` into Go map we can't expect to put the values back in the same order, as the map traversal order in Go is undefined.
This PR extends `array.ApproxEqual` by allowing map keys to be in different order.

### What changes are included in this PR?

New helper functions:
* `array.arrayApproxEqualMap` that is now used instead of `array.arrayApproxEqualList` for map comparison
* `array.arrayApproxEqualSingleMapEntry` that checks if the single map entry we have matches to the other one without having keys sorted the same way

### Are these changes tested?

1. Newly added test `array.TestArrayApproxEqualMaps`
2. https://github.com/cloudquery/cloudquery/pull/11078

### Are there any user-facing changes?

New `array.WithUnorderedMapKeys` option for `array.ApproxEqual` that allows users to control if the entries order is important or not.

* Closes: #35828
