ESQL: Move more test type error testing (elastic#119945)

This reduces the number of test cases in ESQL a little more ala elastic#119678.
It migrates a few random tests and all of the multivalue functions:
```
92775 -> 43760
 3m45 -> 4m04
```

This adds a few more error test cases that were missing to make sure it all
lines up well. And it fixes a few error messages in a few functions. That's
*likely* where the extra time goes.
