[IC] Relocatable IC caches for projects with custom buildDir

Browse Source 
IC caches often contain file paths. To make them relocatable, we need
to convert these file paths into relative paths, relative to a base
directory.
  - If the file paths are source files, we can use the root project
    directory as base.
  - If the file paths are class files, we should use the classes
    directory as base (before this commit, we used the root project
    directory in both cases, that's why we hit KT-58547).

The key changes in this commit include:
  - RelocatableFileToPathConverter: converts paths to relative paths
  - IncrementalCompilationContext: contains 2 different path converters,
    one for source files and one for class files
  - SourceToOutputFilesMap: maps source files to class files using the
    above path converters
  - IncrementalCompilerRunner: creates the path converters based on file
    locations

Test: RelocatableFileToPathConverterTest unit test
      SourceToOutputFilesMapTest unit test
      BuildCacheRelocationIT.testCustomBuildDirectory integration test
^KT-58547 Fixed
