…o PseudoEMetricSpace and add corresponding lemmas for open thickenings (#6194) This PR mainly makes the generalization so that `tendsto_measure_cthickening` and `tendsto_measure_cthickening_of_isClosed` assume `[PseudoEMetricSpace]` instead of `[PseudoMetricSpace]` (the proofs require no changes, but the generality seems valuable). Also the counterparts `tendsto_measure_thickening` and `tendsto_measure_thickening_of_isClosed` for open thickenings (instead of closed thickenings) are added.

This PR mainly makes the generalization so that
tendsto_measure_cthickeningandtendsto_measure_cthickening_of_isClosedassume[PseudoEMetricSpace]instead of[PseudoMetricSpace](the proofs require no changes, but the generality seems valuable).Also the counterparts
tendsto_measure_thickeningandtendsto_measure_thickening_of_isClosedfor open thickenings (instead of closed thickenings) are added.The diffs show almost exactly the same deletions and additions (modulo minor docstring edits). The actual difference is that the
section PseudoEMetricSpace, where the results are moved, has thevariable-line giving the more general assumption compared to thesection PseudoMetricSpace, where the results were originally.
