Fix for Vulkan ray tracing test using a non-zero raygen shader index (#2380)

* Fixed math errors in SBT creation causing a ray tracing test to fail with a fully zero output when given a non-zero raygen shader index

* Removed unnecessary code

* raygen memcpy now copies the 32 bytes from srcHandle and zeroes out the remaining 32 bytes due to 64 byte alignment
