[SPIR-V] vk::SpirvType used as T in vk::RawBuffer APIs causes SIGSEGV

[devshgraphicsprogramming]

Description
Tried to use a sized inline SpirvType for uint8_t with RawBuffer because I couldn't use my own bda::__ref (inline Spir-V PhysicalStorageBuffer class pointer to type T) because of #6951 not being merged yet fixing the Spir-V Type of Spir-V Type issue.

Steps to Reproduce

Godbolt DXC trunk: https://godbolt.org/z/61WsMPzjr

Actual Behavior

Crash with SIGSEGV

My own godbolt instance (a few commits behind) has a Debug build of DXC and I can't see any assert being hit.

Environment

• DXC version: latest
• Host Operating System: whatever you have an Godbolt
