* 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

* Use 1-based argument index for DebugLocalVariable
GLSLANG/DXC NSDI uses 1-based index of the argument. Slang should
follow this convention like other SPIR-V generators.
* format code

* Add command line option for separate debug info
Add command line arg -separate-debug-info which, if provided, produces
both a .spv and a .dbg.spv file. The .dbg.spv file contains full debug
info and the .spv file has all debug info stripped out.
Also add a DebugBuildIdentifier instruction to store a unique hash in
both the output files, so they can be more easily matched together.
A matching API is provided to allow using the Slang API to retrieve a
base and debug SPIRV as well as the debug build identifier string.

This change supports OpDebugTypePointer for a member variable whose type
is a pointer type for the outer struct that hasn't been declared yet.
It is done with new extension, "SPV_KHR_relaxed_extended_instruction",
that comes with a new instruction, "OpExtInstWithForwardRefs".
Closes #4304
