doc: Update documentation about wchar_t

[Bruno Haible]

On 32-bit AIX, wchar_t has only 16 bits. But on 64-bit AIX, it has 32 bits.


2020-01-01  Bruno Haible  <address@hidden>

        doc: Update documentation about wchar_t.
        * doc/*/*wc*.texi: Clarify that 64-bit AIX does not have a too small
        wchar_t type.
