Add DIMM Temperature to LHM. (#1743)

* Add DIMM Temperature to LHM. * Remove RAMSPDToolkit as submodule and use nuget package instead. Upgrade System.Management assembly (required for nuget package). Implement retry mechanism for RAM detection due to possible issue at system boot. * Change to static field. * Driver now back in LHM. Ring0 replaced with OLS implementation. * Update package version. * Undo most of changes. Implement IDriver interface. * Change package to new one. * Review changes. Explicitly set UseWMI (current default is also false). * PR comments: Now having one DimmMemory instance per RAM stick. Separated memory sensors into two new classes. * PR feedback --------- Co-authored-by: PhyxionNL <7643972+PhyxionNL@users.noreply.github.com>
