[FIX] web: restore pointer cursor for all buttons
[FIX] web: restore pointer cursor for all buttons

Since the update to Bootstrap 4.3.1 made with commit
https://github.com/odoo/odoo/commit/4697d7448010376397f7150b84c207978ab3010e,
the pointer cursor is not automatically added on elements with the 'btn'
class but only on <button> elements. This is a strange undocumented
decision as the 'btn' class can be used anywhere, especially on <label>
elements for their checkbox and radio button components as documented:
https://getbootstrap.com/docs/4.3/components/buttons/#checkbox-and-radio-buttons

This commit reenables the pointer cursor for all non disabled elements
with the 'btn' class.
