[Wasm] stdlib API: make kotlin.assert internal

Being disabled by default
 and not well-documented, these functions cause confusion among early
 adopters as to why their code don't work properly.

Assert APIs need a proper design across Kotlin platforms.
 Since APIs are not available in common code and K/JS, it is premature
  to have such a general feature in a new experimental platform.

Compiler tests:
* Mute tests that rely on assert.
* Replace JVM-specific assert calls with require calls and unmute passed K/JS tests.
