scripts: Add ksize.py and dirsize.py
Fixes [YOCTO #5388] These scripts can be useful when working to reduce the size of the Linux kernel and the root filesystem. ksize.py displays the kernel build size by the built-in.o files. dirsize.py displays the various sizes of the components of the root directory.
