[MOV] web: move some DOM utils to the non-lazy loaded bundle
In the future, we might want to make most utils available in the non lazy JS bundle part. We are also considering moving the Bootstrap lib and some more in there. This commit is about moving the strict minimum to be able to improve the lazy loading behavior in stable: the DOM utils that allow to make async handlers and create button loading effects when we click on them. This also means that those utils were adapted to not use jQuery and other non available utils. Related to task-3770362 X-original-commit: 2e922105d8714704b3db94966defc922297e2ab6 Part-of: odoo/odoo#159680
