[sir_richard] 46001: [NTOS]: Implement CmSetLazyFlushState to disable lazy writing in the Cm. [NTOS]: Implement ExSwapInWorkerThreads to in-swap any worker threads when needed. [NTOS]: Add HAL stubs for HalEndOfBoot and HalSetWakeEnable since most HALs set this to NULL. [DDK]: Add some missing definitions.
