gcc: Fix c++: tweak for Wrange-loop-construct

This commit updates the warning to use a check for "trivially constructible" instead of
"trivially copyable." The original check was incorrect, as "trivially copyable" only applies
to types that can be copied trivially, whereas "trivially constructible" is the correct check
for types that can be trivially default-constructed.

This change ensures the warning is more accurate and aligns with the proper type traits.
