Both the Msys2 and Cygwin runtimes make use of
FILE_DISPOSITION_IGNORE_READONLY_ATTRIBUTE in their implementations of the
unlink() system call. This enables these routines to delete a read-only file
without first modifying the attributes.

This is far simpler than drawing with it.

The immediate motivation here is that the DXGI_FORMAT_R8G8B8A8_UINT test causes
a validation error when drawing, since the shader declares its resource as a
float4 texture, which does not match the UINT view format. This could be fixed
by using a different shader, but it seems more prudent to just simplify the test
to not draw at all.

This reverts commit a19c8712.

Fixes both a memory leak and an alloc/free mismatch, and the module heap
is the most appropriate place to hold the variable long-term.

Stops a linker error of duplicate name when using upstream vkd3d.

Only done for DS format.

Add infrastructure to generate fake .PDB files.

Only done in DS format.

I'm not sure we care about JG anymore, DS format has been introduced
by MS in early 2000 to supersede JG, and is still mainstream today).
For the record, LLVM in its PDB handling doesn't support JG format.

NtUserMessageCall(..., NtUserSendDriverMessage) does not ensure the
validity of the hwnd, so this check will incorrectly fail if the
last error was ERROR_INVALID_WINDOW_HANDLE by coincidence. The
notify_owner call immediately following this code will catch a
destroyed owner hwnd.

'if exists' takes a parameter which can be directory, directory/,
directory/. directory\ or directory\. for example, and should equate
to true if the directory exists. The syntax directory\ is explicitly
rejected by FindFirstFile and hence was not working - look for this
specific case, and if found append a '.'.
