feat: add --vaadin-input-field-padding

[BalusC]

Describe your motivation

I'd like to be able to adjust the input field padding suite-wide.

Below is an example showing a text-field, select and text-area which happen to already have a customized background color and border radius and font size via suite-wide CSS properties --vaadin-input-field-background, --vaadin-input-field-border-radius and --vaadin-input-field-value-font-size.

However, I can't seem to find a suite-wide CSS property to adjust the input field padding.

No such thing is mentioned in https://vaadin.com/docs/latest/components/text-field/styling, https://vaadin.com/docs/latest/components/select/styling and https://vaadin.com/docs/latest/components/text-area/styling

Ultimately I'd like to achieve the following padding suite-wide, note especially also the dropdown toggle and textarea autosizing:

Describe the solution you'd like

A new suite-wide CSS property something like --vaadin-input-field-padding would be very welcome in order to accomplish this in a consistent manner.

Describe alternatives you've considered

Of course you can override the host styles, but that's cumbersome and doesn't account for any future components.

Additional context

Using Vaadin 24.4.10.
