Subject: Enable kotlinc flags in blueprint files

Add support for adding kotlinc files in the module.

Some flags are unnecessary as they are added by
default (-no-jdk and -no-stdlib), or are not needed
on an Android build (-include-runtime), or may
conflict with the build (-kotlin-home and
-Xintellij-plugin-root), so the error stops the
build if they are added.

Test: part of java/java_test.go
