Function supportsImmediateData

Checks if the browser supports immediate data (experimental).

Checks for:

• setImmediates method on GPURenderPassEncoder, GPUComputePassEncoder, or GPURenderBundleEncoder prototypes.
• maxImmediateSize property on GPUSupportedLimits prototype.
• immediate_address_space feature in gpu.wgslLanguageFeatures.

This helper is used to skip tests when the environment does not support immediate data functionality.
