Replace reflection-based compiler arguments copying with generated code

Using of Kotlin reflection for simple operations like bean management is very slow

First time initialization time: 261 ms for `copyBean(K2JVMCompilerArguments())`
Subsequent calls of `copyBean(K2JVMCompilerArguments())` take 1.7 ms per call

Unfortunately compiler argument handling is also used in Kotlin IntelliJ plugin
to parse facet settings. Big projects may have thousands of Kotlin facets

The same `ArgumentUtilsKt.copyProperties` frame is seen across various freezes:
IDEA-252440 2-3 minutes freeze on Kotlin project reimporting in last 203 eap
IDEA-253107 A lot of short freezes (1-3 sec) during Kotlin project development
KTIJ-23501 Make main run configuration detection lighter
KTIJ-22435 Unresponsive UI with 100% cpu

Reflection issue:
KT-56358 KClasses.getMemberProperties takes too much time

This commit replaces all reflection stuff with a simple code generation
Now `K2JVMCompilerArguments().clone()` goes to hard-to-measure time
