[libc++] Mark P2845R8 __cpp_lib_format_path and P2587R3 __cpp_lib_to_string as C++26 (#93255)
[P2845R8](https://wg21.link/P2845R8) "Formatting of
`std::filesystem::path`" and [P2587R3](https://wg21.link/P2587R3)
"`to_string` or not `to_string`" are C++26 features, so they should be
marked accordingly in `generate_feature_test_macro_components.py`.

I verified that without my changes, running the script produced no
edits. Then with my changes, I ran the script to regenerate all files,
with no other manual edits.

Found while running libc++'s tests with MSVC's STL, which noticed this
because it's currently a C++23-only implementation.

Note that @H-G-Hristov has a draft implementation of P2587R3: #78100
