Pull Request Overview

This PR adds comprehensive texture and sampler support to the lambda-rs rendering engine. It introduces 2D and 3D texture creation, sampling configuration, and depth testing capabilities, along with tutorial documentation and working examples.

• Implements platform-level texture and sampler builders with proper padding and validation
• Adds high-level API wrappers for textures, samplers, and depth attachments
• Extends bind group system to support texture and sampler bindings
• Provides depth buffer support with configurable clear operations
