[PATCH 35/79] [Backport to 15][DebugInfo] Support translation of DebugFunctionDefinition instruction (#1961)

DebugFunction does not have an Function Id operand in NonSemantic.Shader debug info specification. It's been replaced by the whole new DebugFunctionDefinition instruction to avoid forward references.

This instruction must appear in the entry basic block of an OpFunction.

Specification:
https://github.com/KhronosGroup/SPIRV-Registry/blob/main/nonsemantic/NonSemantic.Shader.DebugInfo.100.asciidoc#DebugFunctionDefinition
