Description

Support compiling Lighthouse with MSVC and executing as a native binary on Windows, without requiring the Windows Subsystem for Linux. Windows support under WSL is covered by #1238

Known Issues

• LevelDB doesn't run on Windows. Soln: RocksDB, LMDB? (Switch on-disk database from LevelDB #483)
• We use some unix filesystem operations, particularly around permissions. Soln: separate permissions code for Windows.
• Probably lots of networking incompatibilities (to investigate)
• milagro_bls uses paths that are not valid on Windows (make fails on Windows due to milagro_bls #1447)
