Allow passing a MessageRenderer to CLITool.mainNoExit

Earlier a system property was used to configure a message renderer
for the K/N compiler. The fix for KT-37550 requires getting rid of
using properties when the compiler is started in a Gradle process.
This patch allows us to specify a correct message renderer at
the K/N side depending on entry point used to run the compiler.
