[meta-zephyr,1/5] Cleanup README.txt files

From: Peter Hoyes <Peter.Hoyes@arm.com>

The README.txt files at the root and in meta-zephyr-core are identical,
so replace the copy inside meta-zephyr-core with "See ../README.txt" to
remove the need to keep two files in sync.

Add a similar README.txt to meta-zephyr-bsp.

I ran this series though CI and it passes

Thanks,
