SQLite shell builder

Builds and publishes SQLite shell for different OS:

• Ubuntu 20.04 shell. Because for some reason "Linux Shell" from SQLite website does not work on Ubuntu.
• Windows shell (64-bit). Because SQLite website only provides 32-bit shell.
• macOS shell (supports both Intel and Apple processors). Just for convenience.
