Alex Dubov e4444cbaaa windows: add NtSetEaFile, NtQueryEaFile and NtQueryInformationFile
unix package already provides support for working with file extended
attributes via Fsetxattr and Fgetxattr syscalls. Windows offers a similar
feature implemented by means of NtSetEaFile and NtQueryEaFile syscalls.
Those syscalls are provided by this patch.

Additionally, NtQueryInformationFile syscall is added. It is required
for correct implementation of extended attribute support in library
code, as correct invocation of NtQueryEaFile relies on file information
returned by said syscall. It also amends the previously accepted
NtSetInformationFile syscall.

Fixes golang/go#78672
