[ATL30] Fix m_szAutoName definition and construction in Wine's ATL30 dll.

Browse source 
- Make the format actually MS-compatible: "ATL" followed by colon,
  followed by hexadecimal digits of pointer.

- The MS counterpart of this DLL was delivered with Visual C++ 6.0 and
  Windows 98+, so obviously it always was 32-bit and they never had a
  64-bit version for it. But we do. So make the size of the m_szAutoName
  buffer cross-compatible.

- See previous commit dbddd878 and the discussion in PR #2010.
