Improve support for CI in Github

[uilianries]

Greetings!

The current CI is broken and failing during the configuration. Plus, it only validates a single build on Linux.

So, in this PR I replaced the previous CI to use Linux, Mac and Windows, to run tests using libinterpolate.

It uses cache feature to re-use build folder when sending PRs, saving more time when building. Plus, Conan packages are cached too.

The configurations used in the CI will be:

• Linux Ubuntu 24.04 + GCC 13 + Conan 2.5.0
• Mac OSX 14 + Clang 18 + Conan 2.5.0
• Windows + MSVC 17 2022 + Conan 2.5.0

There is exclusion rule: When changing docs, README, license, etc, the CI will not run, but those files does not affect the project artifacts.
