Upcoming versions of Clang/LLVM change some behaviour around templating that causes OpenVDB to fail to compile. This commit addresses two issues and allows VDB to compile again. 1. There were three instances of an unnecessary template keyword in NodeManager.h that were not followed by a template call, and therefore are illegal to the compiler. 2. GridBuilder.h had a template call to a non-existent method. This was not previously validated, but is now validated. Switching the symbol from `isActive` to `isOn` per Ken's review. See the [changelog](https://releases.llvm.org/19.1.0/tools/clang/docs/ReleaseNotes.html#improvements-to-clang-s-diagnostics:~:text=Clang%20now%20looks%20up%20members%20of%20the%20current%20instantiation%20in%20the%20template%20definition%20context%20if%20the%20current%20instantiation%20has%20no%20dependent%20base%20classes.) for Clang and the associated [PR for the second point above](llvm/llvm-project#84050) Signed-off-by: Dhruv Govil <[email protected]>
