Include RxDB version details in MongoDB handshake

[alexbevi]

The PR incorporates MongoDB's wrapping client library specification for the connection handshake to allow library details to be included in the metadata written to mongos or mongod logs.

For example, this change would allow server-side logs such as the following:

{"t":{"$date":"2024-01-27T23:10:40.108Z"},"s":"I","c":"NETWORK","id":51800,"ctx":"conn16235","msg":"client metadata","attr":{"remote":"127.0.0.1:1094","client":"conn16235","doc":{"driver":{"name":"nodejs|RxDB","version":"6.12.0|16.0.0"},"platform":"Node.js v18.18.2, LE","os":{"name":"linux","architecture":"x64","version":"5.15.133+","type":"Linux"}}}}

For anyone hosting clusters with connections coming from different applications this can help differentiate connections and facilitate log analysis.

TODO

• Add proper version RxDB version tracking (I'm not sure where to pull this from)

This would be the same type of change as meteor/meteor#13222
