windows: add LockFileEx, UnlockFileEx system calls

Changes in syscall_windows.go were copied from
internal/syscall/syscall_windows.go.

zsyscall_windows.go was regenerated by running
'go generate -tags=generate golang.org/x/sys/windows'
using a toolchain built from tip (after CL 196122).

These functions are called by cmd/go/internal/lockedfile via
internal/syscall/windows. I'd like to copy lockedfile into another
project (CL 197299), but these functions need to be exposed here in
order to do so. We may need these in x/mod eventually, too.
