[IR][cache] Fix for https://youtrack.jetbrains.com/issue/KT-44764

The .konanLibrary is cached for each declaration for performance purposes, but it is only ok to do it
after IR has been lowered to its final state (or at least when declarations aren't being moved around),
so the fix respects that by only taking .konanLibrary of a IrFile (it is assumed that files stay on their place
during entire backend lowering procedure).

-### Dependency verification
+### Including into composite build
 
-We have a [dependencies verification](https://docs.gradle.org/current/userguide/dependency_verification.html) feature enabled in the
-repository for all Gradle builds. Gradle will check hashes (md5 and sha256) of used dependencies and will fail builds with
-`Dependency verification failed` errors when local artifacts are absent or have different hashes listed in the
-[verification-metadata.xml](https://github.com/JetBrains/kotlin/blob/master/gradle/verification-metadata.xml) file.
+To include kotlin compiler into [composite build](https://docs.gradle.org/current/userguide/composite_builds.html) you need to define `dependencySubstitution` for `kotlin-compiler` module in `settings.gradle.kts`
 
-It's expected that `verification-metadata.xml` should only be updated with the commits that modify the build. There are some tips how
-to perform such updates:
+```Kotlin
+includeBuild("/path/to/kotlin") {
+    dependencySubstitution {
+        substitute(module("org.jetbrains.kotlin:kotlin-compiler"))
+            .with(project(":include:kotlin-compiler"))
+    }
+}
+```
 
-- Use auto-generation for getting an initial list of new hashes (verify updates relate to you changes).
+or in `settings.gradle`
 
-`./gradlew -M sha256,md5 help`
-
-*(any other task may be used instead of `help`)*
-
-- Consider removing old versions from the file if you are updating dependencies.
-- Leave meaningful `origin` attribute (instead of `Generated by Gradle`) if you did some manual verification of the artifact.
-- Always do manual verification if several hashes are needed and a new `also-trust` tag has to be added.
-- If you’re adding a dependency with OS mentioning in an artifact name (`darwin`, `mac`, `osx`, `linux`, `windows`), remember to add 
-  counterparts for other platforms.
+```Groovy
+includeBuild('/path/to/kotlin') {
+    dependencySubstitution {
+        substitute module('org.jetbrains.kotlin:kotlin-compiler') with project(':include:kotlin-compiler')
+    }
+}
+```
