Reflection: improve and optimize kotlinFunction/kotlinProperty

- Make the implementations very similar, to fix KT-54833 where the
  companion object case was forgotten for kotlinProperty.
- Optimize both functions to look up the function/property by name
  first, to cover the most probable case when the JVM name of a
  declaration is equal to its Kotlin name. This fixes KT-55937.
