Suggested-by: Ben Boeckel <ben.boeckel@kitware.com>

This commit simplifies the logic checking if builttool target should be
added by adding the variable VTK_COMPILE_TOOLS_IMPORTED.

This commit updates the build systems to allow cross-compiling VTK
using toolchain defining CMAKE_CROSSCOMPILING_EMULATOR.

It simplifies the cross-compilation removing the need to independently
compile the "VTKCompileTools".

See https://cmake.org/cmake/help/v3.8/variable/CMAKE_CROSSCOMPILING_EMULATOR.html#variable:CMAKE_CROSSCOMPILING_EMULATOR

We now provide a nice error message earlier when we detect a sufficient
old compiler that VTK doesn't support.

We now provide a nice error message when the C++ compiler doesn't
support C++11. At the same time I have sneaked in a way for advanced
users that are using compilers not supported by CMake compiler feature
detection to still build VTK.

ES2 is causing headaches and code mess and is
getting old. Remove for 8.0 so we can focus on
more modern APIs. Most Apple and Adroid devices
from the past 4 years support ES3.

CMake 3.7 adds support for cross-compiling to Android without a complex
toolchain file.  Port our main CMake build system to work without the
`android.toolchain.cmake` file:

```
$ cmake ../VTK \
    -DCMAKE_SYSTEM_NAME=Android \
    -DCMAKE_ANDROID_NDK=/path/to/ndk \
    -DVTKCompileTools_DIR=/path/to/vtk-compile-tools \
    -DOPENGL_ES_VERSION=3.0 \
    -DVTK_Group_StandAlone=OFF

Kit mode will build vtk as object libraries, which need to be passed
the correct visibility properties. Because of this, we need to make
sure to only use visibility properties when we have CMake 3.3+
