c66cb76fed Build: Added support for out-of-tree Arch
Introduces the ARCH_ROOT argument, similar to BOARD_ROOT and SOC_ROOT.
This enables support for out-of-tree architectures.

The ARCH_ROOT out-of-tree layout is expected to be the following:
 * ${ARCH_ROOT}/arch/${ARCH}/
 * ${ARCH_ROOT}/include/arch/${ARCH}/ (Optional)

62e55e5e4b Build: Offsets lib as OBJECT not STATIC
With the new cmake version, we are able to simplify the generation of
the offset object library without using absolute hardcoded paths.

Instead of the hardcoded paths, we now use the generator:
$<TARGET_OBJECTS:${OFFSETS_LIB}>

This is needed to eventually be able to have an arch-out-of-tree build

01592071f1 cmake: Toolchain abstraction: security
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.

This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting easier porting to other (commercial) toolchains.

361fdaac1a cmake: Fix the generation of fixup files
A recent change in how the fixup mechanism works caused several
regressions. See
https://github.com/zephyrproject-rtos/zephyr/pull/12680 for more
details about the regressions.

The core of the matter is that using defines to pass on include paths
causes interopability issues when integrating with external build
systems.

To resolve this we re-write the fixup mechanism to instead generate an
aggregated fixup file that is ready to be included at build time. Then
no paths are passed through defines and we resolve the regressions
reported.

c23cc26c73 DeviceTree: Convert 'generated_dts_board.h' into a source file
extract_dts_includes.py has been generating DT output and then
concatenating it with fixup header files to create
'generated_dts_board.h'.

In this patch we instead introduce a source file named
'generated_dts_board.h' and have it \#include the appropriate DT
output and fixup files.

This results in a simpler system because users can now read
'generated_dts_board.h' as C source code to see how fixup files and
generated DT output relate to each other. Whereas before they would
have to either read documentation or python code to gain the same
understanding.

Also, it reduces the scope and complexity of one of our most bloated
python scripts, extract_dts_includes.py.

fb3d201cae cmake: STACK_CANARIES: Re-write how compatibility is checked
This re-write fixes several issues with how we were checking for
compatibility with the canary flags:

If a compiler did not support any stack canaries, but a user had still
enabled them, this would silently result in no canaries being added
instead of error-ing out as it should have.

Compatiblity for '-mstack-protector-guard=global' was unnecessarily
being tested twice, once in 'check_c_compiler_flag' and once in
'zephyr_cc_option'.

Compatibility was being tested with 'check_c_compiler_flag' which is
slower than 'zephyr_check_compiler_flag' because it does not cache
it's results.

1b86fb9da3 cmake: Use variables for target names
There is an effort underway to make most of the Zephyr build script's
reentrant. Meaning, the build scripts can be executed multiple times
during the same CMake invocation.

Reentrancy enables several use-cases, the motivating one is the
ability to build several Zephyr executables, or images, for instance a
bootloader and an application.

For build scripts to be reentrant they cannot be directly referencing
global variables, like target names, but must instead reference
variables, which can vary from entry to entry.

Therefore, in this patch, we replace global targets with variables.

3e784bc6b5 CMakeLists.txt: Enable -fno-common globally.
This is needed to force the .common type to .bss type.
This will force the .common variables to go into bss section
in the compiled object file.
As of now the movement to the .bss section was happening only
during the final linking stage.

The -fno-common option specifies that the compiler should place
uninitialized global variables in the data section of the object
file, rather than generating them as common blocks.  This has the
effect that if the same variable is declared (without "extern")
in two different compilations, you will get a multiple-definition
error when you link them.

e.g:
// file a.c
// file-scope

int b;

// file b.c
// file-scope

int b;

If there exist two non-extern declarations of the same variable
then no-common will cause a linker error.
This sequence would have compiled before, but will now cause a
linker error.

62e152a8f0 cmake: Added rule and helper functions for code relocation.
This patch creates a rule in the cmake to trigger the generation
of linker_relocate.ld and code_relocation.c files.
The linker_relocate.ld will create appropriate sections and will
link the required functions or variables from all the selected
files.
The code_relocation.c will have code that is needed for
initializing data sections and copy of text sections(if XIP).
Also this will contain code that is needed for zeroing of bss.

The procedure to invoke this feature is:
1. Enable CONFIG_CODE_RELOCATION in the prj.conf

2. Inside CMakeList.txt in the project we need to mention
   all the files that needs to get relocated.

   zephyr_kernel_code_relocate(src/*.c SRAM2)

   Where the first argument is the file/files and the second
   argument is the memory where it has be placed.
   NOTE: The file argument supports glob expressions.

NOTE: Step 2 can be done as many times as required. And relative
paths can be given here.
