Stdlib annotation 'kotlin.internal.NoInfer' was redeclared in stdlib tests
so non-fried modules (kotlin-stdlib-jdk7, kotlin-stdlib-jdk8, etc.)
could access it.
IR deserializer does not support declaration duplicates (at least yet
for JS IR backend). Thus this commit removes this redeclaration and
suppresses errors on its usages instead.
