* test/unit/utProfiler.cpp: fix `gcc-16` build failure
Upcoming `gcc-16` improved detection of unused variables as:
test/unit/utProfiler.cpp: In member function 'virtual void utProfiler_addRegion_success_Test::TestBody()':
test/unit/utProfiler.cpp:71:22: error: variable 'j' set but not used [-Werror=unused-but-set-variable=]
71 | volatile int j=0;
| ^
The change is intentional accoring to Andrew Pinsi and is not a faalse positive.
* Update utProfiler.cpp: Remove dead code

The process incorrectly deleted original meshes from the scene when cleaning up after an error if those meshes had been added to its output list (outMeshes). The fix ensures proper ownership transfer by nullifying the original mesh pointer in the scene (pScene->mMeshes[i] = nullptr;) when the mesh is moved to outMeshes. This prevents the scene destructor from attempting to delete the mesh again later, while allowing the error cleanup path in SortByPTypeProcess to correctly delete all meshes it owns (both newly created and transferred originals).

The loader attempted to read the MDL header without verifying if the input buffer was large enough.
Added a check in MDLImporter::InternReadFile_HL1 to ensure the buffer size is sufficient before proceeding with loading.

* Fixed a container-overflow error in `ODDLParser::OpenDDLParser::parseIntegerLiteral` by swapping the order of conditions in a while loop to ensure the end-of-buffer check happens before dereferencing the pointer. This prevents reading past the end of the buffer when lookForNextToken returns the end pointer.

* AC: Support Double-Sided Faces
The AC format marks double-sided SURF elements with the 0x20 flag, which Assimp ignored. This commit adds support for double-sided faces.
On encountering a double-sided face via the flag mentioned above, the front face is generated as usual but is then duplicated. The winding order of the duplicate is flipped to form a back face. Vertices are duplicated too so that back faces work correctly with normal vector generation and face smoothing.
* Add test file
* Simplify test case
