[TypeScript] Improve constructor declarations

[SergeyMaltsev]

Forum post

export class NumberDataField extends DataField {
    /**
     * Base constructor, passes arguments to [construct](https://bryntum.com/products/grid/docs/api/Core/Base#function-construct).
     * @param {object} args Usually called with a config object, but accepts any params
     */
    constructor(...args: object[]);
}

The ideal declaration is like this:

export class NumberDataField extends DataField {
    /**
     * Base constructor, passes arguments to [construct](https://bryntum.com/products/grid/docs/api/Core/Base#function-construct).
     * @param {object} args Usually called with a config object, but accepts any params
     */
    constructor(config?: Partial<NumberDataFieldConfig>);
}

This "problem" exists in almost all DataField classes, this is the "fix" I'm suggesting.
