[BUG] Grid view configuration: Performance problems when searching for object definition fields

[saschabaecher-twocream]

Steps to reproduce

1. open the Pimcore demo
2. expand or create an object definition with many fields (in my case e.g. more than 200 fields)
3. open the grid view
4. open the configuration of the grid view
5. search for any field (see screenshot 1)
6. the search takes a very long time

Screenshot collection:

Actual Behavior

The search cannot be used for large object definitions due to the very long loading time.

Expected Behavior

The expected behaviour would be that the search loads at an acceptable time even with large object definitions.
