FIR/LC: restructure light identifiers

Browse Source 
* introduced KtLightIdentifierBase so that both FIR LC and ULC share
  basic implementations

* detach PsiCompiledElement as per KTIJ-21412,
  while introducing KtLightIdentifierWithOrigin so that
  UastLightIdentifier can still inherit origin computation logic

^KTIJ-21412 In Progress
