Change Description

Streamline the handling of F Prime locations. This provides backwards compatibility for the old variables.

Rationale

Needed to remove dependence on old static CMake structures

Testing/Review Recommendations

CI

Future Work

Unknown.

Pull request overview

This PR refactors how F Prime’s CMake build system tracks “locations/build roots” and global include roots by introducing a single global INTERFACE target that owns these properties, while maintaining backward compatibility with historical location variables.

Changes:

• Introduces a new global interface target (FPRIME_GLOBAL_INTERFACE_TARGET) to carry locations, include roots, and chosen implementations as target properties.
• Updates module naming/build-root discovery and FPP autocoder path handling to consume FPRIME_LOCATIONS from the global interface target.
• Removes the legacy __fprime_config target concept and links BASE_CONFIG configuration modules into the global interface target instead.
