Macro to switch between PERFORMANCE and SILENT while hard-capping velocity

This macro (in principle) allows to hot-switch between performance and silent. It redefines SET_VELOCITY_LIMIT assuming your slicer will use that to set movement limits, and rejects any values that go beyond the set caps. It allows to switch to silent printing without reslicing the model and without loosing steps, at the cost of potentially moving too slow than necessary.
