We also get pre-defined constants instead of carrying our own copies.
However, this changes the public API winio.FileBasicInfo from using
syscall.Filetime to using windows.Filetime, as visible in
backuptar/tar.go.

At this point points of difference between the three local
mksyscall_windows.go implementations and
golang.org/x/sys/windows/mkwinsyscall v0.0.0-20210104204734-6f8348627aad
are:
- pkg/etw: Deduplicates imported functions due to multiple calling APIs
- pkg/security and vhd: Forced UTF-16 mode, not checking A/W suffix. I
also removed cosmetic differences between these two implementations.
`go generate` reports no changes with these updates.

This moves all the current users of
$GOROOT/src/syscall/mksyscall_windows.go to instead use
golang.org/x/sys/windows/mkwinsyscall, as directed by the version of the
former in Go 1.15.
It also syncs the local forks of mksyscall_windows.go with the latest
version of golang.org/x/sys/windows/mkwinsyscall/mkwinsyscall.go, so
that the local patches can be easily seen in a side-by-side comparison.
Significant changes compared to the in-tree forked versions:
* *bool parameters are read back through a temp-var, not directly like
other pointer parameters.
* ?-suffixed function names support testing for function presence before
calling. This replaces a local implementation of this in
pkg/security, which was not actually used anyway. The upstream version
correctly supports functions that don't already have an error return.
* `errnoErr(0)` is now useful, so each call of `errnoErr` doesn't need
to be protected with a check for 0 first.
* The generated functions are now sorted. This of course produced a
*lot* of churn in the generated files.
vhd\vhd.go was changed to generate syscalls into zvhd_windows.go, since
regeneration removes the build tag added by hand in
9d8277341f.
After all that, I also ran
```
go generate . .\pkg\etw\ .\pkg\process\ .\pkg\security\ .\vhd\
```
to update all the existing generated code.

On Windows, the os/exec.{Command,CommandContext,LookPath} functions resolve command
names that have neither path separators nor file extension (e.g., "git") by first
looking in the current working directory before looking in the PATH environment
variable.
Go maintainers intended to match cmd.exe's historical behavior.
However, this is pretty much never the intended behavior and as an abundance of
precaution this patch prevents that when executing commands.
This patch was prompted by the [Go 1.15.7 security fixes](https://blog.golang.org/path-security).

The _docs_ say it returns 0 for failure, non-zero for success.
This implementation is looking for <0 as HRESULT failure, and deriving
an Errno from that.
The new tests fail with GetFileSystemType as it was defined, e.g.,
```
--- FAIL: TestGetFSTypeOfValidButAbsentDrive (0.00s)
fs_windows_test.go:41: GetFileSystemType a:\ unexpectedly succeeded
```
when I definitely do not have an A:\ drive.

This change adds bindings for AttachVirtualDisk and GetVirtualDiskPhysicalPath, some helper functions including
one to create a differencing vhd, exports the create and open parameters, exports the create flags and adds a couple
of missing flags. This will be used mainly to go hand in hand with the new computestorage calls added to hcsshim as all of the
vhd creation and setup needs to be done manually for these calls. https://github.com/microsoft/hcsshim/pull/881.

Since Go 1.6, archive/tar has gained public support for custom PAX
Records, so there's no need to maintain a fork of this library anymore.
We do end up with a fork of the PAX timestamp parsing/formatting
functions, but they are much less likely to change.

When opening a disk it for deatch using 'Version == 2' parameters it is
required that the'accessMask == VirtualDiskAccessNone'. Also updates the
virtual disk 'flag' parameter to match the set specified by the product when
