Description of changes:

• Remove elasticurl project
  • This was an early KMP proof of concept, compiling for JVM and Android. It's no longer necessary now that we're working on a full Kotlin/Native implementation

This brings the repo back down to a single module/project. Should we bump the aws-crt-kotlin project up to the top?

Good idea @ianbotsf , I'll do that in a follow-up PR. We still have two modules right now: aws-crt-kotlin and build-support which contains some KMP-specific utilities that should be refactorable into aws-kotlin-repo-tools soon
