QTypeInfo: Add a missing include

This header uses std::is_trivial_v, which requires including
the <type_traits> header.

When building with PCH enabled (which is the default), this
dependency does get satisfied via the PCH, so no issue is
visible.

This fixes building with recent version of libc++ when configured
with _LIBCPP_REMOVE_TRANSITIVE_INCLUDES (which removes unnecessary
transitive dependencies between the libc++ headers, a configuration
which may become the default in the future), with PCH disabled.

Pick-to: 6.2
