Subject: Handle unset variables in various parts of the codebase (#8944)

DISABLE_UNTRACKED_FILES_DIRTY, DISABLE_AUTO_TITLE, GIT_STATUS_IGNORE_SUBMODULES are not set
Handle these variables not being set with conditional access.

If the user has set -u option to report attempts to use undeclared / unassigned variable, accessing the variables needs to be conditional.
