Added mirroring support for child meshes

[JohnGreenFC]

• Removed old system for requesting reversed index buffers
• Added support to read the transform of a mesh and reverse its index winding based on that

Pull request overview

This PR updates Trinity’s mesh rendering path to support mirrored (reflected) child meshes by selecting reversed index winding at batch-build time based on the mesh transform, removing the prior “request reversed index buffers” mechanism.

Changes:

• Added a reverseWinding/reverseAreas parameter to mesh batch generation so callers can flip winding per draw based on transform determinant.
• Removed the legacy reversed-index-buffer request flow (ReverseIndexBuffers() / RequestReversedIndexBuffers()).
• Updated geometry resource preparation to always generate reversed index buffers and account for their memory cost.

File	Description
trinity/Tr2MeshBase.h	Extends GetBatches signature with reverseWinding; updates CreateGeometryBatch declaration.
trinity/Tr2MeshBase.cpp	Propagates reverseWinding into batch creation; removes legacy reversed-index request logic.
trinity/Tr2MeshArea.cpp	Removes automatic reversed-index-buffer requesting when an area becomes reversed.
trinity/Tr2Mesh.h	Removes ReverseIndexBuffers() override from Tr2Mesh.
trinity/Tr2Mesh.cpp	Removes reversed-index-buffer requesting in geometry resource setters and the ReverseIndexBuffers() implementation.
trinity/Tr2InstancedMesh.h	Consolidates GetBatches overloads and adds reverseAreas default parameter.
trinity/Tr2InstancedMesh.cpp	Removes legacy wrapper overload; keeps a single GetBatches with reverseAreas.
trinity/Resources/TriGeometryRes.h	Removes RequestReversedIndexBuffers() API and the request-tracking flag.
trinity/Resources/TriGeometryRes.cpp	Removes old request-time reversal; always builds reversed index buffers and updates memory accounting.
trinity/Eve/SpaceObject/Children/EveChildParticleSystem.cpp	Removes per-update reversal request (render-time reversal already used).
trinity/Eve/SpaceObject/Children/EveChildMesh.cpp	Computes transform determinant and passes reverseWinding into mesh batch generation for mirrored children and shadows.
