This commit adds a preliminary implementation of CMSIS-Core(R) for use
with the ARM Cortex-R port.
At this time, CMSIS-Core(R) is not merged back into the upstream CMSIS
repository and therefore is not available from official sources.
Until upstream merge happens, the preliminary version can be obtained
from the following URL:

The existing implementation used HAS_CMSIS configuration to specify
that CMSIS-Core(M) is used; when, in fact, there are other CMSIS
variants available such as CMSIS-Core(A) and CMSIS-DSP available.
This commit replaces the existing HAS_CMSIS configuration with
HAS_CMSIS_CORE to clarify that CMSIS-Core is used. It also introduces
the CMSIS-Core variant configuration, HAS_CMSIS_CORE_M, that is
automatically selected when HAS_CMSIS_CORE is enabled.
For more details, see issue #19717.

For CMSIS compilation, we define __PROGRAM_START
to avoid compiling the bss/data initialization
routines provided by CMSIS.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make
