fix(demo64k): Pass absolute time to gpu_draw and remove tempo_test_enabled from main.cc

This commit resolves a bug where effects in demo64k were not showing due to  receiving delta time instead of absolute time. The  parameter to  is now correctly set to . Additionally,  and its associated conditional  block, which are specific to , have been removed from  to streamline the main application logic.
