Dynamic Paramters: Add maskInput styling option for input and textarea form types

[jaaydenh]

• add a styling prop called maskInput
• For parameter of form_type input or textarea, maskInput will convert all characters in the parameter value to *

This is not meant to be secure in any way and simply hide the characters typed into the input

@matifali can you confirm the description has the correct functionality?

Yes. We should also add a show/hide toggle button.
