Add broader Stream API unit tests and VM integration test for edge cases

[shai-almog]

Motivation

• Improve coverage of Stream API edge cases to ensure consistent behavior across the translator/VM and JavaSE, especially for distinct, skip, limit, toArray, empty-stream semantics, encounter order and null handling.
• Add an integration test that compiles a small app, runs it on JavaSE, translates it for the native VM, builds and executes the translated binary, and verifies the outputs match.

Description

• Extended StreamApiTest by adding multiple assertions that exercise distinct(), sorted(), skip(), limit(), toArray(), Stream.empty(), limit(0), skipping past the end, forEach encounter order, empty-stream anyMatch/allMatch/noneMatch semantics, and distinct() with null values, and added the required Consumer import.
• Added StreamApiIntegrationTest (JUnit) under vm/tests which dynamically writes and compiles StreamEdgeApp.java, runs it on the host JVM, runs the translator, uses CMake to build the translated native executable, executes it, and compares the RESULT= line from both runs for equality.
• Added the test resource StreamEdgeApp.java used by the integration test which performs a deterministic series of stream operations and prints a RESULT= checksum.

Testing

• Ran the StreamApiTest unit tests in the hellocodenameone test suite and they completed successfully.
• Executed the new StreamApiIntegrationTest which compiles StreamEdgeApp, runs it on JavaSE, translates and builds a native executable, and compared the RESULT= output from JavaSE and the native run; the integration test passed.
