[flang][runtime] Disable LDBL_MANT_DIG == 113 for the offload builds. (llvm#109339)
When compiling on aarch64 some `LDBL_MANT_DIG == 113` entries end up trying to use `complex<long double>` for which there are no certain specializations in `libcudacxx`. This change-set includes a clean-up for `LDBL_MANT_DIG == 113` usage, which is replaced with `HAS_LDBL128` that is set in `float128.h`.
