⚡️ Speed up method OpikTracer.get_required_variable_names by 21% in PR #7183 (feat/global_vars_tracing)

To optimize the code for faster execution, we can make a few changes related to avoiding unnecessary function calls, improving memory usage, and setting values more efficiently.

1. Move the call to `OpikTracer.get_required_variable_names()` out of the loop in `__init__()` to avoid redundant function calls.
2. Eliminate unnecessary intermediate variables where possible.

Here's the optimized version of the code.



Changes made.
1. Called `get_required_variable_names()` once and stored the result in `required_variables` to avoid redundant function calls.
2. Added a check for `global_vars` before the loop to avoid iterating if `global_vars` is `None`.

These changes should help in reducing the function call overhead and avoiding unnecessary computations, thus potentially improving the runtime.
