To speed up rebuilds, define the NDK_CCACHE environment or CMake variable
to the path to your ccache binary. When declared, the android.cmake.toolchain
automatically uses CCache when compiling any C/C++ source file. For example:

export NDK_CCACHE=ccache

Previously the generator always uses hardcoded list of modules.
This fix replaces hardcoded list with actual set of modules coming from cmake.

fixed MCVC warnings

added texture_binder

All the functions from it are moved to the header
opencv2/photo/photo.hpp
