KT-65684: KAPT: (Re)enable fallback to K1 KAPT and make it default

[KAPT] KT-65684 Set languageVersion=1.9 in KaptToolIntegrationTestGenerated

[KAPT] KT-65684 Re-enable a few now-passing tests in Kapt4IT

[KAPT] KT-65684 Fix the logic setting -Xuse-kapt4 flag in Kapt4IT.forceKapt4()

The change is needed to make sure that all the tests have the flag set,
 otherwise some of them would silently switch to the fallback node.
Also disables a few now failing tests.

[KAPT] KT-65684 Revert "KT-64385 Enable K2 KAPT by default"

This reverts commit 7e9d6e60
