  Log Message:
  -----------
  Reland " [flang] Rely on global initialization for simpler derived types" (#130290)

Currently, all derived types are initialized through `_FortranAInitialize`, which is functionally correct, but bears poor runtime performance. This patch falls back on global initialization for "simpler" derived types to speed up the initialization.

Note: this relands #114002 with the fix for the LLVM timeout regressions that have been seen. The fix is to use the added fir.copy to avoid aggregate load/store.
