Remove the non-LPAC sandbox code on Windows. The restricted token sandbox will not ship, as the LPAC sandbox has been chosen as the sandboxing solution on Windows. This CL removes the restricted token sandbox code, and disables the sandbox on fieldtrial_testing_config because it's not yet ready to ship. This CL also updates the supported version of Windows for the LPAC sandbox to WIN10_RS1 (Version 1607, Build 14393) to match the support offered by the sandbox.

This directory contains platform-specific sandboxing libraries. Sandboxing is a technique that can improve the security of an application by separating untrustworthy code (or code that handles untrustworthy data) and restricting its privileges and capabilities.
Each platform relies on the operating system's process primitive to isolate code into distinct security principals, and platform-specific technologies are used to implement the privilege reduction. At a high-level:
mac/
uses the Seatbelt sandbox. See the detailed design for more.linux/
uses namespaces and Seccomp-BPF. See the detailed design for more.win/
uses a combination of restricted tokens, distinct job objects, alternate desktops, and integrity levels. See the detailed design for more.Built on top of the low-level sandboxing library is the //sandbox/policy
component, which provides concrete policies and helper utilities for sandboxing specific Chromium processes and services. The core sandbox library cannot depend on the policy component.
