[Security Solution][Exceptions] - Remove exceptions table search #88784 (#88784)

## Summary

Temporarily addresses https://github.com/elastic/kibana/issues/88450

A follow PR will address full fix.

### Issue
Exceptions table search not functioning as expected.

### Diagnostic
The exception list SO properties are mapped as keywords, meaning ES does not tokenize them. Need to add a `text` mapping for fields we want to search on in order for search to work as expected. Expectations for exceptions table search being:
- I can search `Endpoint Security` and get results that match `Endpoint` or `Security`
- I can search `"Endpoint Security"` and it will conduct an exact match search

It's too late in the release cycle for mappings updates - a follow up PR will properly fix search.

### Without Search
