Fix test_vulkan_interop_buffer validation errors for Int8 storage shader (#2603)

Fixes vulkan validation layer error:

Vulkan validation layer: Validation Error: [
VUID-VkShaderModuleCreateInfo-pCode-08740 ] | MessageID = 0x6e224e9 |
vkCreateComputePipelines(): pCreateInfos[0].stage SPIR-V Capability Int8
was declared, but one of the following requirements is required
(VkPhysicalDeviceVulkan12Features::shaderInt8). The Vulkan spec states:
If pCode is a pointer to SPIR-V code, and pCode declares any of the
capabilities listed in the SPIR-V Environment appendix, one of the
corresponding requirements must be satisfied
(https://vulkan.lunarg.com/doc/view/1.3.275.0/linux/1.3-extensions/vkspec.html#VUID-VkShaderModuleCreateInfo-pCode-08740)
