Annotate Gradle tasks with @DisableCachingByDefault

Gradle 9.x plugin validation fails the build when a task type is neither
@CacheableTask nor @DisableCachingByDefault. OpenApiTask and AsyncApiTask
are code generators whose spec-file inputs are not declared as cacheable
inputs, so caching is disabled explicitly with a documented reason.
