(#6294) Build sentry-native with CXX 14

* Build sentry-native with CXX 14 since sentry-crashpad, one of its possible dependencies, exposes CXX 14 code on its headers.
This will be addressed in upstream sentry-native
getsentry/sentry-native#574

* Support breakpad and sentry-breakpad as backends

* Add minimum compiler version check / raise.

* Add pkgconf as build_requirement if breakpad is set as backend
