Use aapcs for efiapi calling convention on arm
On arm, llvm treats the C calling convention as `aapcs` on soft-float targets and `aapcs-vfp` on hard-float targets [1]. UEFI specifies in the arm calling convention that floating point extensions aren't used [2], so always translate `efiapi` to `aapcs` on arm.
