bsp: rkbin: add native recipe for tools (ddrbin_tool.py)

This will allow us to use tools from rkbin repo destined to be used on
the host in recipes for the target. For example, ddrbin_tool.py which
is used to modify the configuration of the DDR bin blob.

This has limited usefulness for ddrbin_tool.py as it is a python script
with no external dependencies and could be run directly from
rockchip-ddr-bin recipe. However, this is required so we can decouple
the version of the git repo used for rockchip-ddr-bin DDR bin blob from
the version of the git repo used for ddrbin_tool.py (which is very
recent).

This recipe will be used in a later commit to modify the DDR bin blob if
need be.
