Remove the dependency over embedded-runtimes.

This build dependency won't work anymore with the next GNAT release as
runtimes will now require being installed into the compiler.

This commit also now generates automatically the board projects, to ease
the addition of new boards and runtimes, as well as taking into account
modifications refactoring of the library.
