This is placeholder for extended warning flags, likely to change between
toolchains.
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.

The introduced macros are placeholders for the cmake parameter warning
level.

clang doesn't understand fortify at all, provide no op macro,
in order to handle the request to fortify in a generic way.

In case TOOLCHAIN_HOME isn't explicitly reuqested,
(or indirectly forced with CLANG_ROOT_DIR), detect
any host installed clang in the path.

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.

Introduce toolchain_cc_asm macro to capture toolchain specific flags
related to assembly.
-D_ASMLANGUAGE is kept common for all, assuming -D as define flag is
supported by all compilers (which is almost the case).
No functional change expected.
Clang's flags are compatible with gcc, and are thus inherited.
This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting easier porting to other (commercial) toolchains.

Introduce toolchain_cc_cpp_*-family of macros.
Move the following into the toolchain_cc_cpp_* macros:
* Common base set of flags
* C++ standard version
* RTTI
* Exceptions
These macros must be implemented by every compiler port.
These macros set the respective flags, but leaves logic and control to
the root CMakeLists.txt file.
No functional change expected.
Clang's C++ flags are compatible with gcc, and are thus
inherited.
This is motivated by the wish to abstract Zephyr's usage of toolchains,

Introduce toolchain_cc_optimize_for_* family of macros.
Each macro represents a general optimization class.
Each macro is then responsible for setting an output variable to that
class-of-optimization's flag.
The names of these output variables are decided from the root
CMakeLists.txt.
No functional change expected.
Clang's optimization flags are compatible with gcc, and are thus
inherited.

Introduce the first of the toolchain_cc-family of macros:
toolchain_cc_security_fortify and toolchain_cc_security_canaries.
No functional change expected.
Fortify source is not supported by Clang, but this commit retains
current behavior.

Add missing -lgcc when compiling with ZEPHYR_TOOLCHAIN_VARIANT=host
merely copying some existing code from
'compiler/{clang,gcc}/target.cmake'.
This fixes compilation for the following boards with an x86
microprocessor:
galileo, minnowboard, qemu_x86, qemu_x86_nommu, up_squared,
up_squared_sbl
Compilation of the following boards with an X86_IAMCU microcontroller
still fail with a "cannot find -lgcc" error:
arduino_101, qemu_x86_iamcu, quark_d2000_crb, quark_se_c1000_devboard,
tinytile
This is _not_ a regression because these boards _already_ failed with
"undefined reference to __udivdi3" and other libgcc symbols.

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.
