[POC] Workspace migration builder v2 (#13026)

# Introduction
In this PR we've initialized the `workspace-migration-v2` folder.
Focusing on the builder in the first place.
From now it contains:
- Basic temporary types ( `fieldMetadataEntity` and
`ObjectMetadataEntity` )
- Object actions builder ( create, delete, update )
- Fields actions builder ( create, delete ) ( update coming in a
following PR )

We will still have to handle specific conditions such as:
- Index creation
- Uniqueness addition removal
- Relation

We also need to determine when we want to compute and transpile the
object no field `uniqueIdentifier`

We're aiming to merge this first in order to avoid accumulating code in
this PR
