Projects using Dawn that are compiled with Emscripten may use some of our common headers and utilities. ex.) creating a ShaderModule from SPIR-V. Add handling for __EMSCRIPTEN__ to Platform.h so compiling to WASM works. Also, implement GetExecutablePath on Emscripten as unreachable. This is only ever used to search native paths in the Vulkan backend.
