Replace usage of CONFIG_BUILD_FOR_HOST_UNIT_TEST for IM/DM validation…

… checker (project-chip#35319)

* The flag of CONFIG_BUILD_FOR_HOST_UNIT_TEST is not actually tied to unit testing.

Implement a separate flag to control if we crash on errors for IM/DM
checks or not.

* Update src/app/common_flags.gni

Co-authored-by: Boris Zbarsky <bzbarsky@apple.com>

* make the flag name singular
