…nGH-145038) This undoes a change made as a part of PR 137470, for compatibility with EMSDK 4.0.19. It adds `emscripten_trampoline` field in `pycore_runtime_structs.h` and initializes it from JS initialization code with the wasm-gc based trampoline if possible. Otherwise we fall back to the JS trampoline. (cherry picked from commit 43fdb70) Co-authored-by: Hood Chatham <roberthoodchatham@gmail.com>
