Define DEVELOPER_MODE in developer-mode builds

So that build-time consumers (e.g. feature-test) can detect developer
mode through a single dedicated symbol rather than proxying through
implementation-detail defines like ISC_MEM_TRACKLINES.

9.20 has no meson build; add the define alongside the other developer
defines on the existing STD_CPPFLAGS line in configure.ac.  Originally
landed on main in commit d9aeee7901 ("Define DEVELOPER_MODE in
developer-mode builds").
