The LLJITBuilder interface provides a very convenient way to configure the ORCv2 JIT engine. IncrementalExecutor already used it internally to construct the JIT, but didn't provide external access. This patch lifts control of the creation process to the Interpreter and allows injection of a custom instance through the extended interface. The Interpreter's default behavior remains unchanged and the IncrementalExecutor remains an implementation detail.
