This commit introduces Zephyr SDK CMake config package.
This removes the need for setting ZEPHYR_SDK_INSTALL_DIR and
ZEPHYR_TOOLCHAIN_VARIANT when using Zephyr SDK in Linux.
It also allows to introduces never SDKs without breaking Zephyr.
For example, with this PR, the current Zephyr SDK is 0.11.1 but when
releasing 0.12 then the current Zephyr will no longer built.
This PR moves the Zephyr SDK CMake related code to the SDK and thus
allowing to use newer SDKs, as long as they are backwards compatible.
It also allows multiple SDK installations, and will automatically select
the version closet to the required version.

Allow a given toolchain to specify Kconfig options that might be
relevant to a feature available in that toolchain.
For example, the ARM embedded GNU toolchain supports two variants of
newlib and you select the smaller one via a spec file. We can use a
Kconfig option like HAS_NEWLIB_LIBC_NANO to convey that this feature is
supported by that toolchain.
We look for the toolchain Kconfig in ${TOOLCHAIN_KCONFIG_DIR}/Kconfig,
and default TOOLCHAIN_KCONFIG_DIR to:
${TOOLCHAIN_ROOT}/cmake/toolchain/${ZEPHYR_TOOLCHAIN_VARIANT})
toolchain specific cmake files can override the default if needed.
Additionally tweaked the zephyr/generic.cmake to use
${CMAKE_CURRENT_LIST_DIR} to reduce some duplication.

This forms the foundation for the abstraction of the binary tools,
where the following steps are taken:
- Move binary tool resolving, such as objcopy, objdump, readelf and
so forth, out of compiler definitions and place in a dedicated binary
tools folder with the binary tools supplier as subfolder, similar to
the compiler and linker directories.
- Create binary tool sets, gnu, host-gnu and llvm.
- Each toolchain selects the required set of binary tools by setting
BINTOOLS via its generic.cmake as it also does for compiler and linker.
The intent here is to abstract Zephyr's dependence on toolchains,
thus allowing for easier porting to other, perhaps commercial,
toolchains and/or usecases.
No functional change expected.

This allows for inclusion of out-of-tree toolchain cmake files
relating to compiler and linker for both target and generic
toolchains.
The base path used was ZEPHYR_BASE, instead of TOOLCHAIN_ROOT, thus
making it impossible to load the out-of-tree toolchain specific
cmake files.
In addition, the generic toolchain may now specify a generic cmake
file for the linker, similar to the target toolchain linker.

This adds the necessary bits to utilize the x86_64 toolchain
built by sdk-ng for x86_64 when toolchain variant is either
zephyr or xtools. This allows decoupling the builds from
the host toolchain.
Newlib is also available with this toolchain so remove
the Kconfig restriction on CONFIG_NEWLIB_LIBC.

Host-tools don't unconditionally set TOOLCHAIN_HOME anymore,
but in case Zephyr's SDK toolchain is used, set TOOLCHAIN_HOME.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

We were select host compiler from the generic gcc compiler section which
is used for cross toolchains. This arch should use the host-gcc compiler
definition instead.

Split up the toolchain configuration into two phases, generic and
target. The 'generic' phase configures the toolchain just enough to be
able to preprocess DT files. The 'target' phase completes the
configuration with target-specific configuration.
