fix(types): give explicit type to empty arrays

[kevinmarrec]

Description

Fix types of some places where empty arrays with implicit type would resolve to never[] type instead of any[] and cause TypeScript errors.

Motivation and Context

Running a simple TypeScript project with Vuetify was displaying 5 errors regarding Vuetify types, see below the screenshots.

Screenshots of errors

Weirdly, in editor, we can't see these errors in Vuetify source code but only inside a TS project using Vuetify under node_modules/vuetify/src/util/{file}.ts (it's probably due to some tsconfig.json options).

In TypeScript, empty arrays that have no explicit types are resolving to the type never[], so pushing anything (even of any type) in to this array leads to a type error "Argument of type 'any' is not assignable to parameter of type 'never'."

It can be easily fixed by explicitly defining the array type as any[].

How Has This Been Tested?

Locally in the project I had the 5 errors (seen on screenshots). These changes fixed all of them.
