Fixes adaptive bed mesh probing in Klipper when a wipe/prime tower is used.

When BED_MESH_CALIBRATE ADAPTIVE=1 is used, Klipper relies on EXCLUDE_OBJECT_DEFINE regions to determine the probing area.
Previously, with exclude_object = 0, OrcaSlicer did not emit object definitions, and the wipe tower region could be missing from adaptive probing logic.

Changes

For Klipper G-code flavor, always emit EXCLUDE_OBJECT_DEFINE entries (even if exclude_object is disabled).
Add a virtual EXCLUDE_OBJECT_DEFINE NAME=WipeTower polygon derived from first-layer wipe tower geometry.

Result
Klipper adaptive bed mesh (ADAPTIVE=1) now considers both.
