fix(ui5-input/ui5-multi-input/ui5-combobox/ui5-multi-combobox): min-width and margin

[mindarelus]

We have identified a gap in the min-width implementation of the inputs. Another issue found was the missing top and bottom margin of the input components. With this PR we would like to address these issues and:

• add the missing top and bottom margin of all input components
• create a sample page with all Inputs
• update the implementation of the min-width of the ui5-input/ui5-multi-input/ui5-combobox/ui5-multi-combobox components to follow the design and match the one in UI5.

Hi, I haven't tested the change yet, because I want to wait the final decision from the designers.

--_ui5_input_inner_padding_left_no_tokens and the left padding of --_ui5_input_inner_padding_with_icon are the same values, so remove the redundant CSS
