Rename eigen to eigen_library

[kunitoki]

This pull request updates the handling and naming of the Eigen library integration throughout the codebase, ensuring consistency and clarity in module references. Additionally, it updates a type trait in a static assertion to improve standards compliance.

Key changes include:

Eigen Library Integration and Naming Consistency:

• Renamed the Eigen module from eigen to eigen_library in the module declaration and updated all references accordingly, including in thirdparty/eigen_library/eigen_library.h [1] modules/yup_simd/yup_simd.h [2] [3] modules/yup_simd/types/yup_EigenAdapters.h [4] and thirdparty/bungee_library/bungee_library.h [5].

Code Standards and Type Safety:

• Changed the static assertion in getDataPtrAndSize from std::is_pod_v<T> to std::is_standard_layout_v<T> for improved standards compliance and compatibility with non-POD, standard-layout types (modules/yup_audio_devices/native/yup_CoreAudio_mac.cpp).
