View field create many mutation (#15576)

# Introduction
When creating a view with v2 flag activated in production result in race
condition due to request being slow and //.
That's why we're introducing a batch create on view field here
closing https://github.com/twentyhq/core-team-issues/issues/1836

## In v2
- batch create view field endpoint is available
- frontend will target the new endpoint

## In v1
- batch create view field endpoint is not available
- frontend will stick to old fake batch view field creation loop

## Polish
- use persist view field is quite verbose as contains two data model we
could aim to create an update many view fields in order to standardize
new pattern
