Add license header check

[jiannanWang]

Add license header checker to check for license. Two license header styles: C style (for .cpp, .h, .cu, and .cuh files) and hash style (for .py, .sh files)

C_STYLE_HEADER = """\
/*
 * Copyright (c) Meta Platforms, Inc. and affiliates.
 * All rights reserved.
 *
 * This source code is licensed under the BSD-style license found in the
 * LICENSE file in the root directory of this source tree.
 */"""

HASH_STYLE_HEADER = """\
# Copyright (c) Meta Platforms, Inc. and affiliates.
# All rights reserved.
#
# This source code is licensed under the BSD-style license found in the
# LICENSE file in the root directory of this source tree."""
