Remove memory limit from Kusto emulator

[MattKotsenas]

Description

Remove the default memory limit from the Kusto emulator; setting the limit too low can result in errors when running big queries / ingestion, so devs should set the value if needed.

Added tests to verify that all the default emulator values are covered.

Contributes to #8233.
