cmake: detect sysroot for cross-compile toolchains

Fixes: #49587

Try to detect sysroot for cross-compile toolchain if not specified by
the user with `-DSYSROOT_DIR=<path>`.

First, the C compiler is asked if it knows its sysroot, some C compilers
are able to return the sysroot, as an example:
> $ arm-none-eabi-gcc -print-sysroot
> <path>/bin/../arm-none-eabi
> $

but majority of gcc-based C compilers seems to return empty string:
> $ arm-zephyr-eabi-gcc --print-sysroot
> $

in such cases, the cross-compiler target CMake file will try to discover
the sysroot by searching for libc.a, starting one level up from the
compiler location.

If no sysroot candidate is found, a warning will be printed to the user.
If a single sysroot candidate is found, this candidate will be selected.
If multiply sysroot candidates are found, a warning is printed, and the
first candiate in the list is selected. User may select another
candidate with `-DSYSROOT_DIR=<use-this>`.

license: cleanup: add SPDX Apache-2.0 license identifier

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.

cmake: Split toolchain configuration into pre-and post-DT

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.
