Add option to suppress parameter name inlay hint when argument matches name

[zombiezen]

I noted on Twitter for the new inlay hint feature:

The Rust language server has a nice subtle touch where if the parameter name matches the argument variable given, it skips showing the inlay.

And @hyangah noted in #1631 (comment)_:

It looks like Javascript/Typescript have similars, e.g. javascript.inlayHints.parameterNames.suppressWhenArgumentMatchesName

Adding this option would be great for common parameters like ctx context.Context.
