Don't show inlays for constructors

[KotlinIsland]

class A: ...
a = A()

class B[T]: ...
b = B[int]()

The inlay here is useless noise.

[DetachHead]

the inlay hints should probably still be present if it's inferring a generic from a non-literal value

class Foo[T]:
    ...

value: int = 1

foo = Foo(value) # should have an inlay hint of `Foo[int]`

[DetachHead]

or maybe not, now that we have an inlay hint for the call (#818)
