Placeholder for search input field in the "Select Component"

[ginomariob]

It's not a bug but our application is used in multi languages. So in the latest formio-angular-material version the select component contains a search input. The placeholder of this search input is hardcoded with "Type to search". It would be nice to set the placeholder of this search input in the configuration of the component or hide this search input in the configuration of the component.
