When a Clang Static Analyzer checker is disabled in CodeChecker, clang is invoked with the analyzer-disable-checker flag. This allows the user disabling core modeling checkers such as unix.DynamicMemoryModeling. This causes malfunctioning of depending checkers.

❗ ❗ ❗ Breaking Change: ❗ ❗ ❗
After this patch, modeling and debug checkers (listed with clang -cc1 -analyzer-checker-help-developer)
will not be listed and cannot be disabled through CodeChecker with the --enable and --disable flags.

They can be enabled/disabled through the Clang Static Analyzer specific --saargs flag only.

Github action test cases are failed. I think the problem is that this option is supported properly only by the latest clang. So we should handle this on a version dependent way.

There is a typo in the commit message: chekcers vs checkers. Please update the commit message.
