- Use KeLoaderBlock for registry hive loading.

Browse source 
- Get rid of the CACHED_MODULE array and associated structures and stop using them, get rid of ParseAndCacheLoadedModules. Stop using KeLoadedModules and KeLoadedModuleCount outside of freeldr.c.
- Except for MmInit1, the kernel should now be totally isolated from FreeLDR-specific data.

// Ke:
//
// - FIXES:
// * Stop using CachedModules.
// * Try to make MmInit1 NTLDR compatible.
// * Sanitize some context fields during conversions.
// * Figure out why the DPC stack doesn't really work.
// * Try to make MmInit1 NTLDR compatible.
// * Add DR macro/save and VM macro/save.
// - FEATURES:
// * New optimized table-based tick-hashed timer implementation.
