This MR supercedes !1895 and !3073 as a solution to bug [#50771](https://bugs.winehq.org/show_bug.cgi?id=50771). Rather than fixing the problem of Wine's inability to modify the attributes of read-only files, this patch set instead implements `FileDispositionInformationEx` which the Msys2 and Cygwin runtime libriries can use to avoid needing to modify attributes.
All the flags of `FileDispositionInformationEx` are implemented with the exception of `FILE_DISPOSITION_FORCE_IMAGE_SECTION_CHECK`.
This MR improves upon !3073 by implementing `FILE_DISPOSITION_POSIX_SEMANTICS` and `FILE_DISPOSITION_ON_CLOSE` where the previous MR only implemented `FILE_DISPOSITION_DELETE` and `FILE_DISPOSITION_IGNORE_READONLY_ATTRIBUTE`.

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.

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.

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.
