perfetto: fix compile in G3
perfetto: fix compile in G3

Unfortunately G3 is using a very old version of the standard library
which doesn't support is_trivially_move_constructible. Since the reason
these overloads were introduced in the first place was for constexpr
purposes which we don't really use, get rid of the usage entirely.
