Blake3 unconditionally enables C++ support, which unconditionally
requires C++20 when built with cmake >= 3.12, even when this is not
required.
Fixing this does not look trivial, and rather than botching the build,
just require C++20, available from gcc 8.x onward.

Use of threading requires a C++20 compiler, and the oneTBB
implementation. oneTBB is missing from Buildroot, but a system
one may be used if found.
Even if the default for threading is disabled, explicitly state so,
in case the default changes in the future.
Also disable examples, we don't and won't need them.

As more and more packages are required to build the host ccache package
and therefore they has to be filtered out for ccache dependency the list
growed up.
By adding the variable <PKG>_ADD_CCACHE_DEPENDENCY with the default
value to 'yes' we can remove that dependency for each package that is
needed by ccache by setting the value to 'no'. This can be done in the
package makefile instead of tracking the list in the core pkg-generic.mk file.
This behavior is similar to the skeleton and toolchain dependency.
