Is a dietry source of cholesterol required for muscle growth?

Seeing how cholesterol is a non-essential nutrient, I doubt it is the rate limiting step.

Or, put another way, if you don't consume cholesterol, the body makes its own.

So no.

That is a great question. Muscle tissue must make its own cholesterol. It doesn't use circulating cholesterol for cell membrane repair. This is why cholesterol lowering drugs which interfere with the cholesterol synthesis pathway often cause myopathy even when circulating cholesterol levels remain high. It is also why HMB is helpful when muscle cell damage is high.
