Fix recompilation when batch processing is not triggered

[jjfumero]

Description

This patch provides a fix to avoid continuous recompilation of execution plans that do not use batch processing.
TornadoVM was set to recompile every time, but we only need to recompile under certain conditions only when using batch processing, or when changing the device.

Side note: We need the benchmarking suite for the AERO project.

Problem description

The issue was that the benchmark suite, and therefore, user code, can trigger recompilation over and over again due to a condition for batch processing.
