[Buildroot] [PATCH 1/3] package/blake3: explicitly disable threading & examples

[yann.morin]

From: "Yann E. MORIN" <yann.morin@orange.com>

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, explcitly state so, in
case the default changes in the future.

Also disable examples, we don't and won't need them.

[Buildroot] [PATCH 3/3] package/blake3: add target support

[yann.morin]

From: "Yann E. MORIN" <yann.morin@orange.com>

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.
