In this commit, .ir.txt expectation test data files for the JVM IR
backend are renamed to .txt. This is done as two separate commits so
that Git would recognize that these files were logically moved, not that
the contents of the original .txt files were changed.
#KT-64680
In normal circumstances, it leads to the field `c$delegate` NOT being
generated (see KT-39054). However, it's not the case in kapt in any
mode:
- In the old JVM backend, this optimization is not supported.
- In JVM IR, property initializers are missing in light analysis, so
backend cannot figure out that this property is optimizable.
- In kapt4, backend is not being run, and symbol light classes do not
have information about this optimization.
Overall it doesn't matter much which stub is generated here because the
field is private, the test is added just in case.
Also adds rendering of @Metadata annotations in Kapt3 and Kapt4 tests
(currently disabled for a few tests).
