BlacktempelandPhyxionNL 5027bd9d57 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
