add MeasureTheory.integral_tsupport showing that an integral is equal to its restriction to the support of the integrated function.

motivation: this will be used in #12290 to reduce the integral to the support and enables an estimate by the measure of tsupport and the sup of the function.

Can you also add integral_support similarly? Also, they should probably be named setIntegral_tsupport and setIntegral_support.
