John Lewin 0ab547bb26 Restore ability to attach VS to Android via debugger
- Prevent accidental construction of ProviderSQLite objects inside of ProviderSQLite constructor
 - Initialize .baseLibraryCollection during rootLibraryCollection construction to prevent null reference errors
   caused by access before assignment
 - Remove AddItem -> AddStlOrGcode -> AddItem recursion - Fixes crash due to concurrent writes to default.mcp
 - Add sqlite async methods and supporting logic to ensure disk IO operations aren’t run in parallel
 - Consolidate logic around sample part extraction from StaticData from various areas into a single method
 - Rename that method from SyncCalibrationFilesToDisk to EnsureSamplePartsExist
 - Break apart the large LINQ query into discrete and easier to understand steps
 - Add shared base class for sqlite backed library providers and resuse common code in base
 - Guard against cache deletion during one-time library initialization
 - Discard StreamReader cases in favor of ReadAllText - Ensures .Dispose is always called and is ultra succinct
 - Purge orphaned code
