[ibexa/rector] Backported Ibexa Rector recipe to 4.6

[alongosz]

🎫 Issue	n/a

Description:

This PR backports 5.0 configuration to 4.6. 4.6 branch is already available for ibexa/rector package.
Ibexa 5.0 set contains deprecations that should be removed in 4.6 anyway.

There might be some minor differences (like we deprecated something in 5.0 only). We could approach that in several ways:

• Keep different contents of 5.0 set list between 4.6 and 5.0 branches in ibexa/rector package,
• Keep a copy of the 5.0 set as the 4.6 set with changes,
• Ensure all 5.0 rules are executable on 4.6.

WDYT?

Edit: after today's dry run for the presentation the conclusion was that having IBEXA_46 set would look less confusing in case of 4.6.

Note: ideally we take conclusions as follow up changes, because I need this recipe for Ibexa Summit this week.
