"Find All References" shows all interface implementations instead of specific class method references

[wizardnet972]

When using VS Code's "Find All References" on a class method that implements an interface method, the results include all instances where the method is defined (e.g., in the interface and other implementing classes). However, I expected it to show only references specific to the selected class implementation.

Steps to Reproduce:

1. Create a TypeScript file with the following code:

   export declare interface Transform {
     transform(value: any, ...args: any[]): any;
   }
   
   export class Bar implements Transform {
     transform() {}
   }
   
   export class Baz implements Transform {
     transform() {}
   }

2. Right-click on the transform method inside the Bar class.
3. Select "Find All References" from the context menu.
4. The results include all occurrences of transform, including the interface definition and the implementation in Baz.

Expected Behavior:

VS Code should return only the references specific to Bar's implementation of transform.

Actual Behavior:

The search includes all references to transform across the interface and other implementations, making it difficult to isolate usages of Bar.transform.

Impact on "inferFromUsage"

The behavior also affects TypeScript's "inferFromUsage" feature:

export declare interface Transform {
    transform(value: any, ...args: any[]): any;
}

export class Bar implements Transform {
    transform(value) { }  // <-- Inferred: value is a number
}

export class Baz implements Transform {
    transform(value) { }  // <-- Also inferred as a number, even though Baz is unused
}

new Bar().transform(1);

Since Bar.transform(1) is explicitly called, TypeScript infers value as a number. However, Baz.transform also gets the same inferred type even though it's never used. This suggests that TypeScript applies inference across all implementations of the interface, rather than treating them independently.
