[core] revert to direct-hooking into wininet.dll
* This reverts 3194a4dac4 on account that MinGW's delay loading of
  wininet.dll causes the application to prematurely close.
* Yet another episode of the never ending #1877 saga...

[core] drop direct hooking into dwmapi DLL and use delay-loading instead
* Now that we can delay-load DLLs for both MinGW and MSVC, we can also remove
  the direct DLL hook that was added into dwmapi.dll due to side loading and
  revert to using a direct API call instead.
* This reverts part of e1d864f755.
* Also attempt to silence that damn Coverity warning.

[net] drop direct hooking into wininet DLL and use delay-loading instead
* Now that we can delay-load DLLs for both MinGW and MSVC, we can remove the
  cumbersome direct DLL hooks into wininet.dll (which is vulnerable to side
  loading when not delay-loaded) and revert to using direct API calls instead.
* This reverts part of e1d864f755.
* Also attempt to silence a Coverity warning.

[mingw] use delay loading for DLLs that are subject to side loading
* This reverts much of commits f6ac559f4d and 1947266837
  so that we call the Windows APIs directly again, while ensuring that, by the time we load the DLLs,
  sideloading mitigation has already been applied by the application.
* This is a continuation of #1877, and should help prevent re-introducing side-loading issues when we
  link against new libraries, as well as allow us to drop some of the manual DLL hooking we've been
  doing to prevent it, to clean up the code.
* Note that this is a bit more complex than what the stackoverflow post suggests, because we need to
  create delayloaded libs for both 32-bit and 64-bit, which use a different calling convention and
  therefore need to use different .def files. So there's a lot of gymkhana involved, with Makefiles
  and whatnot, to get us there.
* Also simplify the use of CM_Get_DevNode_Registry_PropertyA() in dev.c since recent versions of
  MinGW now have support for it.
* Also fix 2 small issues in net.c (potential overflow) and format.c (memory leak).
