meta: replace cmake mono-build system with a custom build co-ordinator

every system component now has its own self-contained build system, and a seed file describing the component and its build system and dependencies. a new tool, meadow, collects and uses these seed files to build the components into a full system. meadow also manages the target system root and a host prefix where toolchain tools are installed to. the build system has also been updated to use a new $ARCH-rosetta-gcc compiler, and the patches files necessary to build it have been added to toolchain/cross-compiler.
