libcamera: Add macro to conditionally use [[nodiscard]]
The [[nodiscard]] attribute has been added to C++17. It can thus be used
inside libcamera, but would prevent applications compiled for C++14 to
use libcamera if the attribute was used in public headers.
To offer this feature when the application is compiled with a
recent-enough C++ version, as well as for compiling libcamera itself,
add a __nodiscard macro that expands as [[nodiscard]] when using C++17
or newer.
