gen-platforms.sh: Auto-generate <android/api-level.h>

Auto-generate the <android/api-level.h> header which contains
a single macro definition for the native API level that the code
is built against.

Previously, the corresponding files were stored under
../development/ndk and required manual updating, which is tedious
and error-prone

+ remove obsolete dev-generate-api-levels.sh script
