Missing VUID-VkGraphicsPipelineCreateInfo-Input-06632

This check is like ` VUID-VkGraphicsPipelineCreateInfo-renderpass-06631` (which we have for `VK_EXT_graphics_pipeline_library`) but with `VK_KHR_dynamic_rendering` and sample shading

the "decorates any variable in the Input storage class with Sample" can be found by checking the Fragment Entrypoint `std::vector stage_interface_variables` for and Input variable and add an `spirv::DecorationSet` for `Sample`

Start by comparing the existing VUID-VkGraphicsPipelineCreateInfo-renderpass-06631 check for VK_EXT_graphics_pipeline_library with this VK_KHR_dynamic_rendering case. Inspect the Fragment Entrypoint's stage_interface_variables for Input variables and the Sample decoration; done means the missing VUID-VkGraphicsPipelineCreateInfo-Input-06632 validation is covered.
