Move view in metadata-modules/ and create atomic folder + module for each view entity (#14990)

# Introduction
Preparing view-filter and view-group introduction in v2 core engine
Moving view from `core-modules` to `metadata-modules`

## What happened

### Created dedicated modules for each view entity:
- ViewFieldModule
- ViewFilterModule
- ViewFilterGroupModule
- ViewGroupModule
- ViewSortModule

### Each module is now completely independent with its own:
- Controller
- Resolver
- Service
- Entity

### Created dedicated abstraction metadata module folder for:
- flat-view-field
- flat-view

### Dependencies 
- Eleminated circular dep on ViewModule to all others ones
- Granular import not importing the whole viewModule anymore everywhere
