[java] Remove Json Wire Protocol support

[shs96c]

This PR removes JWP support from the Java bindings, though there are undoubtedly places where supporting classes (eg. those that convert capability names from the JWP to W3C formats) have been left over.

Note that it is likely this will break older clients, as it looks like DriverCommand was mis-encoding the capabilities parameter as a Map rather than a collection of Maps. Before this lands, we should check for that.

Best reviewed on a commit-by-commit basis rather than in one go, but this PR is designed to be squashed before merging.

Should we deprecate DesiredCapabilities along with this PR and tell people to use MutableCapabilities if they have to set things dynamically?

I think we should do it apart... do we need to write some reasoning behind it or even check with other TLC members?

Failing tests are unrelated to this change.

Thank you, @shs96c!
