`ASTOptimiziationTests` -> `ASTOptimizationTests`

The current example `batched('ABCDEFG', n=3) → ABC DEF G` can confuse readers because both, the size of the tuples and the number of tuples are 3.
By using a batch size of n=2, it is clearer that the `n` argument refers to the size of the resulting tuples.
I.e. the new example is: `batched('ABCDEFG', n=2) → AB CD EF G`

… table (#136784)

Fixed-sized types, like ``c_int32``, are currently missing from the fundamental data types table
in the ``ctypes`` documentation. This commit adds them, and  notes that ``c_[u]int8`` is an alias
of ``c_[u]byte``.
