More intelligent hints

[alygin]

Having inlay parameter hints is cool, but sometimes it can bee quite annoying. In mature languages, this feature uses additional rules to hide hints when they are redundant. I don't know all the rules, but here're a few that are obvious:

1. Local variable that is passed as an argument, has the same name as the parameter:

2. There's a single parameter (not counting self in methods) and its name matches the function's name:

3. Functions that start with set_ and have single parameter (not counting self in methods):

In all these cases hints could be safely omitted.

I like the idea of intelligent hints, but I would prefer to be able to switch between all and intelligent hints.

Here's the exact rules that Java uses (they can be found in "Show parameter name hints -> Configure... -> Java") setting:

• White list of name patterns (a couple dozens by default, customizable)
• Do not show if method name contains parameter name
• Show for non-literals in case of multiple params with the same type (off by default)
• Do not show for builder-like methods
