video_core/engines/maxwell_3d: Add is_trivially_copyable_v check for Regs

Browse source 
std::memset is used to clear the entire register structure, which
requires that the Regs struct be trivially copyable (otherwise undefined
behavior is invoked). This prevents the case where a non-trivial type is
potentially added to the struct.
