[executorch][cmake] Add EXECUTORCH_ENABLE_LOGGING and EXECUTORCH_ENABLE_PROGRAM_VERIFICATION

These flags should be off by default in Release mode, but some users may want to enable them.

This sets a convention for future options like this, which should also use `${_default_release_disabled_targets}`.
