SpirvShaderDebugger: Have Function inherit LexicalBlock

`debug::LocalVariable` expects the parent scope to contain a `debug::LexicalScope`. If it doesn't, then the variable is never registered, and doesn't show up in the watch windows. DXC emits `DebugLocalVariable`s for parameters, with the parent scope set to the immediate function, with no lexical block. To make parameters show up, make `debug::Function` inherit from `debug::LexicalBlock`. This makes all the existing logic that uses `debug::find<debug::LexicalBlock>()` work for both `DebugLexicalBlock` and `DebugFunction` scope types.
