Don't publish wasm targets with KotlinJsCompilerAttribute

Currently JS/IR and WASM targets share this attribute.
This causes issues for HMPP projects on
Variant-resolution stage when both JS/IR and WAS published.
Given the fact that WASM compilation uses IR only it is logical
to exclude such attribute which should fix variant resolution in HMPP
