djsollen efe46d2094 Repurpose Release_Developer BUILDTYPE and remove SK_DEVELOPER.
The Release_Developer build type is now used to build Skia with
release level optimizations but still enable SK_DEBUG. This in turn
means that SkASSERTS and SkRTConf are available in this mode.

Further we can then remove SK_DEVELOPER as a define as it is true
iff SK_DEBUG is true.
