Allow input value to be copied to selected rows instead of all rows

[PoornimaVKrishnan]

This PR is focussing on applying change to selected forms instead of all forms.
Selected forms will have a border to show it is selected.

• Implemented Select All and a button Apply and Clear to apply and discard the changes to selected forms.
• Added overlay to the form to make it clickable
• Moved the action buttons to next line
• Added indeterminate state for checkbox if not all forms are selected
• On load fist form is active showing it is clicked

I'm going to close this PR since we asked for more UI changes. You can create another PR later when we think the UI is finalized.
