[gpio_controllers] Fix crash on NaN state values and sanitize inputs

[Ishan1923]

This PR attempts to address Issue #1970 ("Boolean data type signals are not supported by GPIO Controller"). Users were encountering crashes and exceptions when reading states, likely due to uninitialized values or type mismatches.

I have introduced a sanitize_double helper function to handle state readings.

Approach & Reasoning:
Instead of a hard cast to bool, this function detects NaN (uninitialized memory) or invalid values and defaults them safely to 0.0. This stops the crashes while preserving the original double value if valid.

This supports both use cases:

• Boolean logic: Works as expected (Values like 0.0 and 1.0 pass through).
• Analog logic: Remains supported (Values like 3.1 or 5.0 are preserved).

I have also updated the ReproduceBadCastCrash test case to EXPECT_NO_THROW to verify that these edge cases are now handled gracefully.

Resolves #1970

Hi @JavierIntermodalicsKion, thanks for checking in! The PR is fully ready and tested on my end. Currently, I am just waiting for a maintainer to approve the CI workflows (since I am a new contributor, they don't run automatically) and for a code review. Fingers crossed we can get this merged soon!
