Backend example does not compile

1

dpnp/backend/examples/example_bs.cpp can not be compiled because interface of dpnp_divide_c has changed

Lack of compile time options in backend tests

1

run by ``` export DPNP_BACKEND_TESTS_ENABLE=1 ./0.build.sh ``` main backend files compile options looks like: ``` dpcpp -DDPNP_LOCAL_QUEUE=1 -DMKL_ILP64=1 -DONEDPL_USE_PREDEFINED_POLICIES=0 -DPSTL_USE_PARALLEL_POLICIES=0 -D_FORTIFY_SOURCE=2 -D_GLIBCXX_USE_TBB_PAR_BACKEND=0 -O3 -DNDEBUG -fPIC -W -Wextra -Wshadow -Wall -Wstrict-prototypes...

Random module

TBB dependency

Currently libtbb.so used for the C++ backend library. Need to try to replace it with sequential library (performance sensitive).

Mathematical functions
