Inconsistent padding/marging on formElements

[aurorascharff]

Padding/margin around formelements should be removed/standardized. It becomes hard to keep confident spacing when using many form elements in a form.

Examples show that i.e mdinput mdtextarea have margin, where as i.e select does not.

In addition, spacing between label and field is inconsistent between i.e MdSelect and MdInput. MdSelect uses 0.5rem as a padding bottom on the label, where as on MdInput its 0.7 rem as a margin on the inout.

Check the md designsystem and see if there are irregularities there as well.
