GH-33317: [C++] Utility method to ensure an array object meetings an alignment requirement (#14758)

This PR adds a utility function which is responsible for ensuring that all the buffers of an arrow object are properly aligned. It checks all the buffers in an arrow object for alignment, and if not aligned properly, then allocates a buffer by specifying the required alignment and copies data from the previous buffer.
* Closes: #33317
