Instead of always generating __wasm_apply_data_relocs when relevant options like -pie and -shared are specified, generate it only when the relevant relocations are actually necessary. Note: omitting empty __wasm_apply_data_relocs is not a problem because the export is optional in the spec (DynamicLinking.md) and all runtime linker implementations I'm aware of implement it that way. (emscripten, toywasm, wasm-tools) Motivations: * This possibly reduces the module size * This is also a preparation to fix https://github.com/llvm/llvm-project/issues/107387, for which it isn't obvious if we need these relocations at the time of createSyntheticSymbols. (unless we introduce a new explicit option like --non-pie-dynamic-link.)
