[SDK:ATL] Fix the size of the ATL_WNDCLASSINFOW::m_szAutoName member according to the actual MS-compatible auto-generated window class name.

Browse source 
The autogenerated name has the format:
    "ATL:<hexadecimal_digits_of_pointer><NULL-terminator>"

and the number of hex digits in 0xABCD1234 (for 32-bit == 4-byte)
pointers (without the '0x') is 8 == 4*2, and for 64-bit == 8-byte
pointers (e.g. 0xABCDEF0123456789) is 16 == 8*2.
