kernel/arch: streamline thread user options

Browse source 
The K_<thread option> flags/options avaialble to users were hidden in
the kernel private header files: move them to include/kernel.h to
publicize them.

Also, to avoid any future confusion, rename the k_thread.execution_flags
field to user_options.
