Pull Request Overview

This PR adds comprehensive unit test coverage for three new Intel XE GPU 2D block operation APIs: XE_PREFETCH_2D, XE_LOAD_2D_VNNI, and XE_LOAD_2D_TRANSPOSE. All tests are conditionally compiled for IGC version 2.18 or higher.

• Validates API declarations and compile-time constraints for VNNI and transpose operations
• Tests prefetch operations with uint8, int16, and float data types
• Ensures proper integration with the existing CuTe tensor framework

Integer division may produce incorrect results. Since sizeof_bits_v<Element> returns bits and is being divided by Bits, this should use floating-point division and rounding, or the multiplication order should be changed to (Width * Bits) / sizeof_bits_v<Element> if calculating elements from bits.

Suggested change

	constexpr int N = Width * sizeof_bits_v<Element> / Bits;
	constexpr int N = (Width * Bits) / sizeof_bits_v<Element>;
