[Tests][JS] Don't use codegen helpers for JS diagnostic tests

[Vladimir Sukharev (vsukharev)]

Don't use codegen helpers for JS diagnostic tests,
otherwise, KOTLIN_PACKAGE_USAGE error diagnostic will be raised for helpers fail.kt, asserts.kt, arrayAsserts.kt, which contain line package kotlin, which is

• recently prohibited in ^KT-85764
• not needed for diagnostic tests

Rationale: in master, JsDiagnosticsWithIrInlinerTestGenerated, LightTreeJsKlibDiagnosticsTestGenerated and PsiJsKlibDiagnosticsTestGenerated are red with messages

KOTLIN_PACKAGE_USAGE: Only the Kotlin standard library is allowed to use the 'kotlin' package. at fail.kt:(0,14)

It isn't shown in Aggregate CI, due to exclusion of JS ES5 tests from Aggregate CI, in scope of
KTI-3244 Duty (18 May - 24 May) .
See

• JSCompilerTestsES5_LINUX are in Quarantine
• no ES5 tests at all in current aggregate, even for Windows

Due to absence in Aggregate, these testrunners were overlooked in scope of ^KT-85764.
This PR fixes them by removing the following codegen helpers from JS diagnostic tests, and adding them only to JS codegen tests:

• JsAdditionalSourceProvider
• CoroutineHelpersSourceFilesProvider

On the way, abstract classes for ES6 codegen tests were streamlined

Note: As next steps, it worth returning ES5 testrunners to Aggregate CI, due to upcoming 2.4.20-Beta2 branching.
