Description
This is a follow on PR from #5304. After extensive testing with my ERCF + wipe tower I'm raising this PR to extend the use of the wipe tower maximum purge print speed to the sparse layers of the tower.
Increasing this speed again offers a significant time saving compared to the stock 90mm/sec especially in layers where there is no tool change as they are slowed down for no reason at all.
My testing with the V2.4 + ERCF shows speeds in the region of 180-200mm/sec are reliable as long as nozzle ooze is adequately controlled during the tool changes. If it isn't, the default 90mm/sec speed should be used throughout the wipe tower anyway to reduce the impact of nozzle collisions with the nozzle ooze.
Updated tool tip reflects the above recommendation.
With these two changes in this and the previous PR I've managed to shave off around 5 hours from a 24 hour print
Before these 2 pr's

Tests
2x 24 hour+ MMU prints over the past week. No nozzle collisions at 180mm/sec and a significantly reduced print duration.
Purge tower was flawless:
