Add DebugGlobalVariable instructions to SPIR-V output (#7686)

* Add DebugGlobalVariable instructions to SPIR-V output

Implements generation of DebugGlobalVariable instructions for global variables
like Texture2D and SamplerState in SPIR-V debug information output. Adds debug
type support for texture and sampler types using DebugTypeComposite.

* Handle two more types for DebugGlobalVariable

kIROp_RaytracingAccelerationStructureType and
kIROp_SamplerComparisonStateType had to be handled in
`emitDebugTypeImpl()`

* Fix format

* Refactor debug type emission to reduce duplication

Use IRSamplerStateTypeBase type check and fallback pattern instead of
separate cases for each opcode type.

* Fix compiler warning

* Simplify `emitDebugTypeImpl()` more
