Multiple bottom layers on wipe tower to improve build plate adhesion on tall prints with the prusa XL

[MaximilianBuegler]

Is your feature request related to a problem? Please describe.
My wipe tower came off the build plate multiple times during very tall prints on my Prusa XL, even when printing with a massive brim.

Describe the solution you'd like
I believe having multiple bottom layers on the wipe tower (or the brim around it) would increase adhesion to the build plate preventing my tall prints from failing.

Describe how it would work
Adding a parameter to specify the number of bottom layers for the wipe tower

Describe alternatives you've considered
I tried increasing the brim and line spacing of the wipe tower, but the single bottom layer just doesn't seem enough when the tower gets > 20cm tall.
