Implement Enso-specific assert

[Akirathan]

Closes #5973

Pull Request Description

Implement Enso-specific assert - Runtime.assert that works like asserts in any other runtime.

Important Notes

• Enso-specific assertions are enabled when JVM assertions are enabled, or when ENSO_ENABLE_ASSERTIONS env var is not empty (See

  enso/engine/runtime/src/main/java/org/enso/interpreter/runtime/EnsoContext.java

  Line 139 in 72cd836

  isJvmAssertionsEnabled() || System.getenv("ENSO_ENABLE_ASSERTIONS") != null;

  )

Can we ensure that we enable the ENSO_ENABLE_ASSERTIONS env var on the CI?

Sure, I added it to the task list so that I don't forget about it.

Two questions:

• please justify use of Assertion for a non-dynamic state.
• do we really need new Enso CLI parameter?

Replace InteropLibrary with EqualsNode or co. Otherwise OK.

Ó, hamcrest... I expect to find some advanced JUnit magic below!

Assertions on the CI will be enabled in #7929
