[KQL] Support single-character wildcard #126532

Describe the feature:

KQL currently supports wildcard queries using the * character to denote "zero or more characters". It does not support ? to denote "one character". It would be nice if it supported both.

Describe a specific use case for the feature:

For example, if I'm interested in all response codes from 400-409, I could do something like 40? .
