Needed for Age of Wonders 4.

When any of these flags:
- PFD_DRAW_TO_WINDOW
- PFD_DRAW_TO_BITMAP
- PFD_SUPPORT_GDI
- PFD_SUPPORT_OPENGL
are set on the PIXELFORMATDESCRIPTOR parameter to ChoosePixelFormat(),
the returned pixel format must also have them set, but when they are
unset, the returned pixel format may or may not have them set.

Also add support for filtering on all these flags. In particular, the
lack of filtering on PFD_SUPPORT_GDI, was causing (at least) Java 1.3
to fail to initialize graphics, because we were returning a pixel
format without the PFD_SUPPORT_GDI flag it asked for.

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=7767

Mingw targets export all symbols by default if there is no explicit
export. We generate export table in winebuild and don't use explicit
exports. This may make linker generate an unused export-all table.

Spotted by Gabriel Ivăncescu.

Creating a view with an unaligned offset is legal in d3d and
apparently works, both on Windows and Linux, but may violate the
Vulkan specification:

VUID-VkBufferViewCreateInfo-offset-00926(ERROR / SPEC): msgNum: -833749292 - Validation Error: [ VUID-VkBufferViewCreateInfo-offset-00926 ] Object 0: handle = 0x3c000000003c, type = VK_OBJECT_TYPE_BUFFER; | MessageID = 0xce4dfed4 | vkCreateBufferView(): VkBufferViewCreateInfo offset (36) must be a multiple of VkPhysicalDeviceLimits::minTexelBufferOffsetAlignment (16). The Vulkan spec states: offset must be a multiple of VkPhysicalDeviceLimits::minTexelBufferOffsetAlignment (https://www.khronos.org/registry/vulkan/specs/1.2-khr-extensions/html/vkspec.html#VUID-VkBufferViewCreateInfo-offset-00926)

Without any reason to test unaligned buffer views here, just resolve this by changing the test.

Both the Msys2 and Cygwin runtimes make use of
FILE_DISPOSITON_POSIX_SEMANTICS in their implementations of the unlink()
system call. This enables these routines to behave similarly to POSIX where are
unlisted from the directory, if handles are still open.

In order to implement FILE_DISPOSITION_POSIX_SEMANTICS, it will be necessary
to add additional flags to closed_fd. In preparation for this, the unlink
member variable has been replaced with disp_flags which directly reflects the
flags defined in the FILE_DISPOSITION_INFORMATION_EX structure.

The FILE_DELETE_ON_CLOSE can be used with the FILE_DISPOSITION_ON_CLOSE flag
of FileDispositionInformationEx.

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.
