This PR partially fixes #33620, #81854

This PR doesn't get us all the way there because of a problem with vscode-sqlite3. (Essentially, it doesn't build with right version of Visual Studio - 2017 or later is needed, the node-gyp config is slightly wrong and I don't have legal approval to fix it). Once that issue is fixed, you'll be able to do the following to build for Windows on Arm, assuming Node v12.13.1 and node-gyp 5.0.5:

set npm_config_arch=arm64
yarn install --force
yarn run gulp vscode-win32-arm64-archive

Make sure to set up an ARM64 cross-compilation terminal as documented in Electron's upstream instructions.

The result is a zip file which you can manually install and run on the device - seems to work well, built-in extensions like syntax highlighting, PowerShell prompt all seem to function, performance is good too.

PTAL and I'll try to fix any non-SQLite issues which come up. CC @deepak1556

Update: 2020-March-10: the revised SQlite3 module has been published.
