Add compile flag to enable mathematical functions (sin, cos, log, pow, sqrt, etc.) in SQLite queries through ProxySQL's SQLite interface. Issue: #5261
Summary of ChangesHello @renecannao, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request integrates advanced mathematical function support into ProxySQL's embedded SQLite by enabling a specific compilation flag. This enhancement allows users to perform complex calculations directly within their SQL queries, significantly boosting the analytical and administrative capabilities of the system. The change is designed to be seamless, ensuring full backward compatibility and a negligible increase in binary size, thereby improving functionality without introducing overhead or breaking existing features.

Code Review
This pull request enables mathematical functions in the embedded SQLite by adding the SQLITE_ENABLE_MATH_FUNCTIONS compilation flag. The change is straightforward and correctly implemented in deps/Makefile.
While the change itself is correct, I've noticed that no new tests have been added to verify that the mathematical functions are indeed available and working correctly after this change. I strongly recommend adding a simple test case, for example in the admin interface, that executes a query with a math function (e.g., SELECT sqrt(4)) to ensure the feature is enabled as expected.
I've also left a suggestion to improve the readability of the Makefile.

For better readability and maintainability, consider breaking this long line of compilation flags into multiple lines using backslashes. This makes it easier to see all the enabled SQLite features at a glance and simplifies adding or removing flags in the future.
