This commit introduces the ability to create and test sparse resources in the Vulkan backend. Key changes: - **Vulkan Backend**: Updated the Vulkan implementation to support sparse binding and residency for buffers. - **Test Infrastructure**: Enhanced test/lit.cfg.py to automatically detect and expose all boolean Vulkan features from api-query as lit features. This enables tests to use REQUIRE for specific hardware capabilities like sparseBinding and sparseResidencyBuffer. - **New Tests**: Added a suite of feature tests in test/Feature/Sparse/ to verify sparse resource behavior across different buffer types, including residency checks and partially mapped resource loads. This provides the necessary framework to validate sparse resource handling and residency behavior in HLSL-to-Vulkan pipelines.

This is irrelevant no? (We assume main queue supports it), since we take a queue with the sparse bit.
