What is the current behavior?

Two issues:

1. Using certain fill settings on ion-input led to dead space. This was happening because padding was being added to .input-wrapper. When clicking that padding, you were clicking neither the label nor the input which meant that the input was never focused.
2. Text was not overflowing when using a fixed label.

What is the new behavior?

• The .input-wrapper element is now the label ensuring that there is never any dead space (This is valid usage: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/label). This also removes the need to explicitly add htmlFor on <label>.
• Added CSS and changed the structure of the label text to ensure that text in the fixed label overflows correctly.

Does this introduce a breaking change?

• Yes
• No
