BREAKING: Remove support for .wasm imports (#5135)

Importing .wasm files is non-standardized therefore deciding to
support current functionality past 1.0 release is risky.

Besides that .wasm import posed many challenges in our codebase
due to complex interactions with TS compiler which spawned
thread for each encountered .wasm import.

This commit removes:
- cli/compilers/wasm.rs
- cli/compilers/wasm_wrap.js
- two integration tests related to .wasm imports
