Removing the lock icon from the password input.

[mpRegalado]

Description

When using components from the forms library, they often accept the prop prepend that can be used to add a component to the side, such as an icon.

When using it in the EuiFieldPassword component, however, it can lead to a duplication of the lock icon, without any way to remove the embedded one that does not match the style of other fields.

Proposed solution

A prop for EuiFieldPassword that allows rendering the component without this icon
