Prebuilt scala package for 2.12

[clouds56]

Description

I found there's prebuilt jar for scala 2.11, now 2.12 is popular and 2.13 has come out. I think it is a good time to provide prebuilt package for scala 2.12 (or even make it the default one).
I tried to built it myself, but I have to keep multiple java version, since the tool required for build javah is removed in jdk 10 (I'm using jdk 12).

Environment info (Required)

For Scala user, please provide:

1. Java version: (java -version) 12.0.2+10
2. Maven version: (mvn -version) 3.6.1
3. Scala runtime if applicable: (scala -version) 2.12.8

Build info (Required if built from source)

Compiler (gcc/clang/mingw/visual studio): clang 8.0.1

I've locally build 2.12 version, I want to help with this issue but I need some guidance about the current build package and how to go ahead with it.
Could you guys please guide me as to how can i start on this??

@atiqsayyed If you want to start on this, we mostly need to update the scala maven build. Right now, we have a profile "scala-2.11". We would want to create a similar profile for scala-2.12 to switch between the versions. We should move the scala.version and scala.binary.version properties into those profiles as well so it can be changed. Then, see if it can actually build both versions.

Newbie to MxNet,

Can anyone tell me if it is possible to build for 2.13?

TIA
