URL: https://github.com/apache/arrow/issues/33864

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   ```
   panic: runtime/cgo: misuse of an invalid Handle
   
   goroutine 17 [running, locked to thread]:
   runtime/cgo.Handle.Value(...)
   	/usr/local/go/src/runtime/cgo/handle.go:124
   github.com/apache/arrow/go/v11/arrow/cdata.releaseExportedArray(0x55889925b4d0)
   	/root/go/pkg/mod/github.com/apache/arrow/go/v11@v11.0.0-20230123220137-8449c553710a/arrow/cdata/exports.go:104 +0x1b8
   ```
   
   We saw this in ADBC as well: https://github.com/apache/arrow-adbc/commit/5029f7b8ed1e60dd7d41f175af0abee6ccadb02e Experimentally, heap-allocating the Go Handle would avoid this at the cost of an extra indirection. That makes sense; the documentation for Handle states:
   
   ```go
   // Some C functions accept a void* argument that points to an arbitrary
   // data value supplied by the caller. It is not safe to coerce a cgo.Handle
   // (an integer) to a Go unsafe.Pointer, but instead we can pass the address
   // of the cgo.Handle to the void* parameter, as in this variant of the
   // previous example:
   ```
   
   (https://github.com/golang/go/blob/master/src/runtime/cgo/handle.go)
   
   ### Component(s)
