Port to Windows (non-WSL)

[michaelfig]

At least the dependency on swing-store-lmdb currently prevents running on Windows natively, as importing the lmdb module results in unresolved symbols. Venemo/node-lmdb#151 (comment) may have a fix.

SwingSet needs synchronous reads of the database in order to function. Perhaps we should use swing-store-simple under Windows natively.

Solved with a patch to node-lmdb:

Agoric/agoric-sdk#2494 plus current Pledger is enough to get working under Windows.
