 * Utility class providing convenient methods for OpenCL device discovery and information queries.

 * 
 * <p>Key functionality includes:
 * <ul>
 * <li><strong>Device enumeration</strong>: Discover available devices on OpenCL platforms</li>
 * <li><strong>Property queries</strong>: Retrieve device characteristics and capabilities</li>
 * <li><strong>Type conversions</strong>: Convert between OpenCL native types and Java types</li>
 * <li><strong>Buffer management</strong>: Handle memory allocation for OpenCL information queries</li>
 * </ul>
 * 
 * <p>Common usage patterns:
 * 
 * <pre>{@code
 * // Enumerate devices on a platform
 * int deviceCount = DeviceUtils.numDevices(platformId);
 * List<cl_device_id> deviceIds = DeviceUtils.getDeviceIds(platformId, deviceCount);
