#5855 Added a way to check triangles for all lods

[akleshchev]

• Added lod level fields to the 'more info' (adavanced) floater.
• Improved update mechanism to avoid excessive refreshes and to avoid setting drawables from draw
• Fixed advanced floater, it become too tight since 26.2 changes (after font became bigger)
• Small cleanup

Pull request overview

Adds per-LOD triangle counts to the Object Weights ("Advanced") floater and reworks the refresh flow so that selection/mesh-related updates happen via an idle callback driven by LLSelectMgr::mUpdateSignal and the active mesh LOD request counter, instead of being computed and applied inside draw(). Also generalizes the volume LOD triangle-count helper and removes an unused signal connection member from LLSelectMgr.

Changes:

• Add LOD INFO section (High/Medium/Low/Lowest triangles) to floater_object_weights.xml and corresponding member text boxes / loading-indicator toggle in LLFloaterObjectWeights.
• Replace per-draw refresh with onIdleRefresh + dirty flags driven by mUpdateSignal and LLMeshRepoThread::sActiveLODRequests, deferring getSelectedObjectRenderCost() out of the coroutine callback.
• Generalize LLVOVolume::getHighLODTriangleCount into getLODTriangleCount(S32 lod) and add LLViewerObject::recursiveGetLODTriangleCount(...).

File	Description
indra/newview/skins/default/xui/en/floater_object_weights.xml	Widens floater, adds LOD-info section with 4 LOD triangle counts and loading indicators.
indra/newview/llvovolume.h / llvovolume.cpp	Adds getLODTriangleCount(S32 lod); getHighLODTriangleCount() now delegates to it.
indra/newview/llviewerobject.h / llviewerobject.cpp	Adds virtual getLODTriangleCount and recursiveGetLODTriangleCount helper.
indra/newview/llselectmgr.h / llselectmgr.cpp	Removes unused mSlectionLodModChangedConnection member and its disconnect.
indra/newview/llfloaterobjectweights.h / .cpp	Adds idle-driven refresh, dirty flags, selection signal connection, LOD UI wiring, and moves render-cost computation out of the coroutine callback.
