Add new widget to display layout Radio button with Image

I fixed fatal error in Edit form, also I did some enhancements on the design.

• Support Gin, Claro
• Create general style
• Add default and fullback image

Hi
I've tried to reproduce issue

Steps :

1. Navigate to the Layout Library module's add form.
2. Observe the absence of an image upload field.

The MR 14 is applied cleanly....
Test Result:
1. Add Form
Image filed is present with upload file and Custom image path.
2. an Edit Form
Image filed is present with upload file and Custom image path.
3. Radio Button option not available.

Styling improvements in gin theme.
