docs: changes: better document Python needs
Python is listed as an optional dependency, but this is not
true, as:
1) arm (multi_v7_defconfig and other defconfigs) and arm64 defconfig
needs it due to DRM_MSM dependencies;
2) CONFIG_LTO_CLANG runs a python script at scripts/Makefile.vmlinux_o;
3) kernel-doc is called during compilation when some DRM options
like CONFIG_DRM_I915_WERROR are enabled;
4) allyesconfig/allmodconfig will enable CONFIG_* dependencies
that needs it;
5) besides DRM, other subsystems seem to have logic calling *.py
scripts.
So, better document that and change the dependency from optional
to mandatory to reflect the current needs.
