GH-39013: [Go][Integration] Support cABI import/export of StringView (#…

…39019)

### Rationale for this change

The Go implementation should support import/export of the new data types. This will enable integration testing between the C++ and Go implementations.

### What changes are included in this PR?

Added import/export for the new data types and arrays of data of those types.

### Are these changes tested?

Yes, they will be covered by the integration tests and existing Go unit tests.

### Are there any user-facing changes?

This is a user facing change

* Closes: #39013
