Add build parameter to build coroutines with JVM IR compiler (#2389)

* Add build parameters to enable JVM IR and disable native targets
    * enable_jvm_ir enables JVM IR compiler
    * disable_native_targets disables native targets in train builds
    * enable_jvm_ir_api_check enables JVM IR API check (works only if enable_jvm_ir is set)

* Fix "Return type must be specified in explicit API mode" in 1.4.20
