cc519a09 - [Embedded] Identify more places to emit symbols even with deferred code generation

[Embedded] Identify more places to emit symbols even with deferred code generation Deferred code generation only produces symbols when they are needed. Expand this out to cover more of the cases where we need them: * @c/@_cdecl with and without @implementation * @_expose(Cxx) and @_expose(Wasm) * @_section and @_used * (already present) the main entry point Part of the Embedded Swift linkage model. Also fixes #74328 / rdar://147207945 along the way.
