now, we do not depends LLVM_ENABLE_BINDINGS and LLVM_INCLUDE_DOCS module
so disable it! if later depends on this module, need upgrade
third_party/llvm-project/ to 12 to compat build env which install
llvm-12-dev

(os vesion >= sp2) build with cmake
* cmake build support(xp sp2):

xp sp2(x86) do not support vc runtime fully, casused by KERNEL32.dll do not
implement some base apis for c++ std function, for example,
std::mutex/std::thread/std::condition_variable as a workround, we will
disable some MegEngine features on xp sp2 env, for exampe, multi-thread etc!
* about DNN_MUTEX/MGB_MUTEX/LITE_MUTEX, if your code will build in inference
code (even CPU backends), please replace std::mutex to DNN_MUTEX/MGB_MUTEX,
* about multi-thread, if you code need multi-thread support, please
enable it when MGB_HAVE_THREAD=1
* about test build env status
1: Visual Studio 2019(MSVC version <= 14.26.28801)---- pass
2: Visual Studio 2019(MSVC version > 14.26.28801) ---- failed
caused by this 'new' version will put VCR depends on win7
KERNEL32.DLL, this may be fixed at Visual Studio 2019 later version
but we do not test at this MR merge point
3: Visual Studio 2017 ---------- pass
4: Visual Studio 2014 ---------- pass

* support arm-host and x86-cross-arm
* fix trt myelib cmake build issue at 'trt copy env'(about 'copy env', Please refs cb92123f)
about x86-cross-arm CUDA env:
1: run ./scripts/cmake-build/create_cuda_build_libs.py to prepare
cuda/cudnn/trt env(download deb package info, Please refs create_cuda_build_libs.py)
2: export TRT_ROOT_DIR=xxxxx which may create by step 1
3: export CUDNN_ROOT_DIR=xxxx which may create by step 1
4: export PATH=xxxx:$PATH xxxx need create by step 1, which nvcc have
relative path dir: ../targets/sbsa-linux/

`copy` env vs `normal` env:
case a:`normal` env install CUDNN/TRT by package tool, eg, apt/yum, which
will put include file(cudnn.h/NvInfer.h) to /usr/include etc.
case b: self copy env after export CPATH with cudnn/trt include dir
case c: just copy libs, not export CPATH, only export
TRT_ROOT_DIR/CUDNN_ROOT_DIR
at case a and case b, BUILD system can find cudnn/trt headers, but
at case c, can not find. `FIX` it!
what`s more, recommend install CUDA env by case a and case c, NOT
recommend install by case b, which caused by CUDA SDK CPATH not
friendly to split c env, for example Android AOSP build env

Also, upgrade to CMake 3.13.
The commit also contains significant refactors, as otherwise it is not
possible to properly export target `megengine` to
MegEngine-targets.cmake:
1. Optionally use system provided Flatbuffers.
2. Optionally use system provided MKL-DNN (Tested with Debian).
3. Refactor megbrain and megdnn targets into object libraries.
4. Set different path in BUILD_INTERFACE and INSTALL_INTERFACE of
various target_include_directories.
5. Specify PUBLIC/PRIVATE on various target_link_libraries.
