Pull Request Overview

This PR reorganizes driver host tests by removing the separate cuda_tests crate and integrating test infrastructure directly into zluda. Additionally, it fixes bugs in pointer host code related to error handling and attribute retrieval.

• Consolidates test infrastructure by removing the cuda_tests crate and moving functionality into zluda/src/tests.rs
• Improves error handling in pointer attribute functions by using unwrap_or for graceful degradation
• Adds comprehensive test coverage for pointer attribute edge cases

This code has undefined behavior. It reads from an uninitialized pointer at line 68, then conditionally writes to it at line 69. The read operation accesses potentially garbage memory. Consider initializing the target memory or using a different approach to check if initialization is needed.

Suggested change

	if (*(data_ptr.cast::<hipDeviceptr_t>())).0.is_null() {
	*(data_ptr.cast::<hipDeviceptr_t>()) = ptr;
	}
	*(data_ptr.cast::<hipDeviceptr_t>()) = ptr;

This code reads from uninitialized memory at line 78. The *data_ptr.cast::<hipMemoryType>() dereferences a pointer that may contain garbage data, passing undefined values to to_cu_memory_type. This could lead to unpredictable behavior.
