[I] [C++] Add Compute Kernel for Casting from list_view to list [arrow]
llama90 opened a new issue, #39051:
URL: https://github.com/apache/arrow/issues/39051
### Describe the enhancement requested
This is a sub-issue of the issue mentioned below.
* #35560
As we can see in the parent issue, we can find tables organizing the related functions.
| file name | code snippet |
|-------------------|--------------------------------------------------------------------------------------------|
| scalar_test.cc | `EXPECT_OK_AND_ASSIGN(auto cast_scalar, scalar.CastTo(to_type));` |
| scalar_test.cc | `scalar.CastTo(to_type));` |
> The functions require handling "Unsupported cast from list_view<item: int16> to list using function cast_list" error.
We need to implement casting from `list_view` to `list`.

### Progress Update
#### Fix CheckInvalidListCast for TestMapScalar
I'm investigating an issue where tests pass locally (Macbook M1), but a Segmentation fault occurs in a [different environment](https://github.com/apache/arrow/actions/runs/7307958925/job/19914144901?pr=39353).
