newlib: stdatomic: implement missing "op_fetch", "nand" builtins

* Adds implementations of __{atomic,sync}_nand_fetch_n. These builtins
  were implemented for other operations but were not defined for NAND.
* Adds implementation of __atomic_OP_fetch_n for all OPs.
* Adds implementation of __sync_OP_and_fetch_n for all OPs.
