Devicetree fixup files existed previous to the current stable Devicetree
API. While they served their purpose, they are no longer necessary nor
used in-tree. This patch drops support for this legacy feature.

Create a cmake/modules folder containing all Zephyr CMake modules.
All Zephyr cmake files that are included from boilerplate are now
converted into CMake modules which can be individually loaded.
The Zephyr CMake package is updated to support loading of individual
CMake modules using the COMPONENTS argument to `find_package(Zephyr)`.
If the COMPONENTS argument is not specified, the default Zephyr build
system will load.
If COMPONENTS is specified then, only those components and the
dependencies will be loaded.
If a Zephyr CMake module depends on another CMake module which has not
been loaded, it will automatically be loaded.
This allows us to modularize and reuse individual parts of the Zephyr
CMake build system in a more flexible way in future.
Such usage could be:
- Higher livel multi image build system
- Invocation of individual components, for example dts processing by
twister without loading all build code
- Doc build
- Unittesting
With this new CMake package and CMake module scheme then direct
sourcing of boilerplate.cmake has been deprecated.
