[PATCH v2] catch2: new package

[PATCH v2] catch2: new package

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Add a recipe for the catch2 testing framework. There's a bug upstream
which makes it impossible to build with gcc7 so include a patch.

---
v1 -> v2:
- upstream merged a different solution for the build error: backport
  the relevant patch, include Upstream-Status tag
- use ${datadir} instead of hardcoded paths
- depend on python3-native, not python-native
- replace ALLOW_EMPTY_${PN} = "1" with RDEPENDS/RRECOMMENDS

+Subject: [PATCH] Fix convert from char on ARM build
+
+Some platforms set the signedness of char to unsigned (eg. ARM).
+Convert from char should not assume the signedness of char.
+
+Fix build issue with -Werror,-Wtautological-unsigned-zero-compare flags.
