Configure pytest to fail CI on any warnings except PendingDeprecationWarning. This prevents the codebase from accumulating warnings like the 1500+ we recently had to clean up. - Add -Werror flag to pytest in both build and examples jobs - Add -Wdefault::PendingDeprecationWarning to keep these as warnings - Simplify examples job warning configuration for consistency

Summary
Configure CI to treat all warnings as errors (except
PendingDeprecationWarning) to prevent warning accumulation and enforce immediate fixes.Motive
Mesa recently had 1,514 warnings across 366 tests, creating technical debt and degrading developer experience. While significant cleanup has reduced this to ~22 warnings, we need to prevent regression.
Without enforcement, warnings slowly accumulate as contributors add code that triggers new warnings. By the time someone notices, hundreds of warnings have built up, making cleanup overwhelming. Treating warnings as errors catches issues immediately at PR time when they're easiest to fix.
Implementation
Added
-Werror -Wdefault::PendingDeprecationWarningflags to pytest in both CI jobs:-Werror: Converts all warnings to errors, failing the build-Wdefault::PendingDeprecationWarning: ExemptsPendingDeprecationWarning, as listed in our deprecation policy.This means
DeprecationWarning,FutureWarning,UserWarning, andRuntimeWarningwill now fail CI, forcing contributors to fix them before merging.Simplified the examples job configuration to match the main build job for consistency.
