Switch product configs from make to ckati

This speeds up dumping make variables from ~380ms using make to ~220ms
using ckati. It also means that we're consistently using the same parser
for builds (with the same .KATI_READONLY/etc extensions).

envsetup.sh (lunch) / other scripts still use make, changing those to go
through soong_ui will be a future change.
