[MCU] how did Bruce Banner survive the fall onto the Bifrost Bridge?

Death isn't instant. It's not like a switch that just turns off, it's a gradual process. So when Bruce landed, he likely would have died in the coming seconds.

But he transformed into the Hulk sooner than he died, which comes with physical regenerative abilities. In fact, the Hulk's desire to live can outspeed the process of death, as we've seen with Banner's suicide attempt.
