System.Data.SQLite -> Microsoft.Data.Sqlite

Seems to be a sort of successor / "modern variant" of System.Data.SQLite? netstandard2.0 so great for us I suppose. I assume it works for Linux? (System.Data.SQLite didn't lol). A quick testing of commands seems to say it works on Windows at least.

Also would eliminate another .NET Framework dep (see #2261).

Check if completed:

• I have run any relevant test suites
• I, the committer, have read the licensing terms for contributors (last updated 2022-07-15) and am compliant

Works under Mono on NixOS, without host SQLite lib even.

Microsoft.Data.Sqlite doesn't attempt to use the host SQLite lib, rather it tries to bundle a build which has a custom naming scheme (e_ prefix). With the latest commit I prevent it from trying to do that directly (as it ends up creating some runtimes folder which doesn't work out) and just put its builds (i.e. relevant e_sqlite3.dll and libe_sqlite3.so builds) in the Assets folder.

FWIW the System.Data.SQLite we had was a mixed assembly with effectively a windows x64 copy of the sqlite dll bundled into it, which would have not work on Linux in any case.
