Remove antd from CreateTokenForm

Thought this would just be a few inputs when I started this diff, but turns out we have some real ancient stuff in here.

• Replace inputs with new cashtab inputs, and update error state methods to best fit them
• Replace legacy dragger (and update ancient npm pkg it was using)
• Simplify upload handling functions and improve error notifications for non-png, non-jpg uploads
• Allow modal to scroll if content exceeds height (as height can be variable with longer token names)
• Expand use of standard Cashtab buttons vs weird custom buttons
• Delete components from EnhancedInputs that are no longer used

Test Plan:
npm test

Mess with the token icon creation form

• try to upload an icon that is not a png or a jpg
• zoom/rotate an icon
• change icon after uploading
• create a token with an icon
