[WIN32K]

- Remove an ASSERT in DC_Cleanup
- Improve code in PDEVOBJ_vSwitchPdev (code shamelessly stolen from Jerome's earlier commit)
- Fix up GDIINFO in PDEVOBJ_bEnablePDEV instead of EngpCreatePDEV
- Update TODO.txt

-# Lock the PDEV lock only when we are going to touch the PDEV or the Surface
-  Currently the PDEV is locked (shared HSEM == ERESOURCE) when we lock the DC,
-  this is only a minimal implementation, as we don't need to do that, when we
-  don't even touch anything from the PDEV or the surface. This should be
-  optimized. (see dc.h, DC_LockDc)
