selftests-dyndbg: add a dynamic_debug run_tests target
This commit adds a dynamic-debug selftest script that modifies pr_debug()
flags and checks their effects. It also integrates dynamic_debug into the
kselftest framework's TARGETS list.

Will this work reliably when selftests are installed and run on a target
device? When tests are run via make install on a target, the source tree's
.config won't be available.
If the .config is missing, the script defaults to LACK_DD_BUILTIN=0, which
may cause false test failures if the target kernel doesn't actually have the
config enabled. Could runtime indicators be checked instead of build-time files?

• echo "# consulting KCONFIG_CONFIG: $KCONFIG_CONFIG"
• grep -q "CONFIG_DYNAMIC_DEBUG=y" $KCONFIG_CONFIG ; LACK_DD_BUILTIN=$?
• grep -q "CONFIG_TEST_DYNAMIC_DEBUG=m" $KCONFIG_CONFIG ; LACK_TMOD=$?

  +function handle_exit_code() {
• local exp_exit_code=0
• [ $# == 4 ] && exp_exit_code=$4
• if [ $3 -ne $exp_exit_code ]; then

•    echo -e "${RED}: $BASH_SOURCE:$1 $2() expected to exit with code $exp_exit_code"

• [ $3 == 1 ] && echo "Error: '$error_msg'"

•    exit $exp_exit_code

Does this mask test failures? If the actual exit code ($3) does not match
exp_exit_code (which defaults to 0), the script calls exit $exp_exit_code.
Since exp_exit_code is typically 0 when expecting a command to succeed, the
script will exit with 0 upon encountering an error, silently hiding the failure
from the kselftest framework.

  [ ... ]
  +function check_match_ct {
• pattern="\s$1\s"
• exp_cnt=0
• [ "$3" == "-r" ] && pattern="$1"
• let cnt=$(ddgrep "$pattern" | wc -l)
• if [ $V -eq 1 ] || [ "$3" == "-v" ] || [ "$4" == "-v" ]; then

•    echo -ne "${BLUE}" && ddgrep $pattern && echo -ne "${NC}"

• fi
• [ $# -gt 1 ] && exp_cnt=$2
• if [ $cnt -ne $exp_cnt ]; then

•    echo -e "${RED}: $BASH_SOURCE:$BASH_LINENO check failed expected $exp_cnt on $1, got $cnt"

•    exit

Does this also mask test failures? Calling exit without arguments returns
the status of the last executed command.
Since the echo command immediately preceding it will succeed with a 0 exit
code, the script exits with 0 and the kselftest framework will incorrectly mark
the failed test as passed. This same pattern appears to be used in several
other functions in the script.

• else

•    echo ": $cnt matches on $1"

• fi

What did you expect to happen?

given its warning, I expected a crash, but hoped for a discussion.
