Currently IDF_VERSION_* variables are not available to the component
CMakeLists.txt files at the requirements expansion stage. This makes
it harder to write component CMakeLists files compatible with
different IDF versions.
Include version.cmake from the requirements expansion script, add a
build system test.
Fixes an issue with Python 3 in MSYS where it fails while trying to join
paths where one part is Unicode (default string on Python3) and the
second part are bytes (returned by the subprocess call).

As reported on forum:

split() with no arg will match any whitespace sequence not just
a single space, so takes care of case where two spaces are
inserted in the variable value.
... to reduce the number of simultaneously open files at link time.
When plugin support is enabled in the linker, BFD's (and the
corresponding file handles) are cached for the plugin to use. This
results in quite a large number of simultaneously open files, which
hits the default limit on macOS (256 files).
Since we aren't using LTO now, disable it explicitly when invoking the
linker.

Use rev-parse to get the HEAD directory instead of manually looking for
it. This method works in the main repository, worktrees and submodules.

This commit makes it so that BUILD_COMPONENT holds only the component,
and a new property BUILD_COMPONENT_ALIASES hold the full name of the
component.
This also removes erroneous check for duplicate components, as this can
never happen:
(1) if two components have the same name but different prefixes,
the internal names are still unique between them
(2)if two components happen to have the same name and same prefix, the
latter would override the former
Previous implementation only builds list of components included in the
build during component registration.
Since the build components is known as the requirements expansion is
ongoing, update the list here instead.
Use imported library, which does not create additional rules, but still
allows attaching arbitraty properties instead of custom targets. This
allows the targets to not appear in the target list of IDEs such as
CLion.

This change allows RTTI to be enabled in menuconfig. For full RTTI
support, libstdc++.a in the toolchain should be built without
-fno-rtti, as it is done now.
Generally if libstdc++.a is built with RTTI, applications which do not
use RTTI (and build with -fno-rtti) could still include typeinfo
structures referenced from STL classes’ vtables. This change works
around this, by moving all typeinfo structures from libstdc++.a into
a non-loadable section, placed into a non-existent memory region
starting at address 0. This can be done because when the application
is compiled with -fno-rtti, typeinfo structures are not used at run
time. This way, typeinfo structures do not contribute to the
application binary size.
If the application is build with RTTI support, typeinfo structures are
linked into the application .rodata section as usual.
Note that this commit does not actually enable RTTI support.
The respective Kconfig option is hidden, and will be made visible when
the toolchain is updated.
Fixes an issue where if idf_build_process is called in a CMake
subdirectory, menuconfig looks for the mconf-idf binary in the wrong
place (in the subdirectory build dir instead of root binary dir).
