This commit implements the `[WaveOpsIncludeHelperLanes]` attribute for the SPIR-V backend. When this attribute is applied to a shader entry point, the compiler will: - Add the `SPV_KHR_maximal_reconvergence` and `SPV_KHR_quad_control` extensions. - Add the `QuadControlKHR` capability. - Add the `MaximallyReconvergesKHR` and `RequireFullQuadsKHR` execution modes to the entry point. This change also includes new tests to verify the correctness of the implementation and updates the documentation. Fixes microsoft#7334
