BC breaks	no

Introducing strict getters for LookupLimitationResult for the issue detected by PHPStan in ibexa/admin-ui#1197.
Alternatively we could add @property-read PHPDoc, but as agreed, we're no longer doing magic.

Also added strict properties. Reasoning: given the class already has declared strict types and the properties can be set only by strictly-typed constructor, it shouldn't be possible to have code which would set something else for these properties.

Checklist:

• Provided PR description.
• Tested the solution manually.
• Provided automated test coverage.
• Checked that target branch is set correctly (main for features, the oldest supported for bugs).
• Ran PHP CS Fixer for new PHP code (use $ composer fix-cs).
• Asked for a review (ping @ibexa/engineering).
