+ Set label for ImGui::BeginCombo as ("##" + label).c_str() to avoid control conflicts, when several combos are placed in one imgui window.
+ Return TRUE value only when selection was changed
+ Added label_width and item_width input parameters to have possibility set a width to the label text and combo control.
+ GizmoCut: Use ImGuiWrapper::combo to render comboboxes

Fixes#9467#9519#9646
Also fixed variable layer height editing for case such as mentioned
in the github issues above.
Also likely fixed some of the sinking objects issues.

Based on the unfinished idea of @supermerill, defining ExtrusionRole
as a bit mask of ExtrusionRoleModifier.
Because the ExtrusionRole was used for both ExtrusionEntity and
G-code export / G-code viewer, the original ExtrusionRole had to be split
to ExtrusionRole and GCodeExtrusionRole to support bitmask attributes
for the former while keeing a low number of ordinary values for the latter.
Some files have whitespace changes that make resolving conflicts difficult.
Take the version from master first, next commit will apply changes from master_250
