Update for node Node 21, update AppVeyor and tests

[acalcutt]

This is a merge of #649 #711 and #709 as requested by #649 (comment)

This PR updates node-pre-gyp to support up to Node 21.
1.) I updated abi_crosswalk.json to include node 21 with 'npm run update-crosswalk'
2.) It adds test coverage for cases of unsupported/unknown targets from #649
3.) It adds building with msvs 2022 and get AppVeyor to pass, from #709

Known Issues
Some tests are failing in node 20 and 21 for what look like minor line ending issues or slight path differences (which seem like differences in the responses from the node versions used more than a real issue with node-pre-gyp)

Testing
I have been using an updated abi_crosswalk.json in @acalcutt/node-pre-gyp and have used it with maplibre-native package up to node 20 (not to 21 only because we are only supporting lts releases)

Note from my own fork testing
Do not publish this from windows, it messes up the line endings in abi_crosswalk.json and makes the package fail on linux.

Does anyone ( @cclauss ) have any ideas for the node 20 appveyor errors? node 18 seems to run fine but node 20 gets some tests failures that look like possible line endings (\n) issues

Failing tests are an extra \n at the end.

an extra "\n" where though

I made this change, but i'm not sure it is corrent since it seemed only lts releases were listed here before
