Share code between engine and stdlib

As pointed out in this comment, we should investigate how (and if) to share code between engine and std libs. Now, this includes something from std-bits/base

Maybe introduce a library that is independent of engine and provides some specialization for primitives?

Some examples where std-bits duplicate functionality from the engine:

• std-bits/base/src/main/java/org/enso/base/ObjectComparator.java
  • Should delegate to LessThanNode.

Tasks:

• [ ] Ensure the shared text utilities between engine and std-base use shared backing code
• [ ] Ensure that hashing in std-table is consistent with engine hashing

Parts of this were done as #5855 - this gives us the shared library which allows for having common code used both on engine and polyglot libraries side.

However, we still need to ensure that the hashing and object comparison/equality mechanism used in the in-memory Table library is delegating to the same code that the engine uses - so that we can avoid code duplication which may lead to potential inconsistency.

The places to look at in particular (not necessarily an exhaustive list):

• ObjectComparator.java
• MultiValueKeyBase.java and its 2 implementations: OrderedMultiValueKey and UnorderedMultiValueKey,
• MatcherFactory.java.
