test(compiler-cli): improve testing harness for incremental compilation (#25275)

In tsc 3.0 the check that enables program structure reuse in tryReuseStructureFromOldProgram has changed
and now uses identity comparison on arrays within CompilerOptions. Since we recreate the options
on each incremental compilation, we now fail this check.

After this change the default set of options is reused in between incremental compilations, but we still
allow options to be overriden if needed.
