Lucas Bordeau ea1ac3708c Implemented view filter group CRUD hooks and utils (#10551)
This PR implements hooks and utils logic for handling CRUD and view
filter group comparison.

The main hook is useAreViewFilterGroupsDifferentFromRecordFilterGroups,
like view filters and view sorts.

Inside this hook we implement getViewFilterGroupsToCreate,
getViewFilterGroupsToDelete and getViewFilterGroupsToUpdate.

All of those come with their unit tests.

In this PR we also introduce a new util to prevent nasty bugs happening
when we compare undefined === null,

This util is called compareStrictlyExceptForNullAndUndefined and it
should replace every strict equality comparison between values that can
be null or undefined (which we have a lot)

This could be enforced by a custom ESLint rule, the autofix may also be
implemented (maybe the util should be put in twenty-shared ?)
