INAPPLICABLE_LATEINIT_MODIFIER.

Also changed FE1.0 checker and all related fix factories to report error
on the declaration instead of the lateinit modifier. This is consistent
with the direction of all checkers in FIR (no reporting on modifiers).

mistakenly removed in 690fb47c.

^KT-44839 fixed

Now Gradle additionally prints warning message regarding using debug
logs that wrapped in '####*' lines.

It is not possible to make it work via reflection.

Since Gradle 6.4 error message was changed, when dependency does not
provide all required attributes.

This format was slightly changed starting Gradle 6.6. Adapted
tests to use new expected output when current Gradle runner is greater
then 6.5.

This property was introduced in 2018 and no longer supported.
See https://discuss.kotlinlang.org/t/how-to-set-usefallbackcompilersearch/9039
for details why it was introduced.

This ensures that compiler classpath is what is expected
by Kotlin Plugin and removes possibility of leaking wrong jars
from Gradle wrapper classpath.

For 'kotlin.useFallbackCompilerSearch' old behaviour is still present,
but this option should be marked as deprecated and removed in one
of the Kotlin releases.

- Don't print upper bounds if it contains only kotlin/Any?
- Print variance in lowercase

Before that, such warnings weren't reported as the corresponding errors were reported during type inference (only original types took part there)
