PR libstdc++/86756 add std::filesystem::path to libstdc++.so
Move the C++17 std::filesystem::path definitions from the libstdc++fs.a archive to the main libstdc++ library. The path classes do not depend on any OS functions, so can be defined unconditionally on all targets (rather than depending on --enable-libstdcxx-filesystem-ts). The tests should pass on all targets too. PR libstdc++/86756 * config/abi/pre/gnu.ver (GLIBCXX_3.4): Make various patterns for typeinfo and vtables less greedy.

PR libstdc++/71044 optimize std::filesystem::path construction
This new implementation has a smaller footprint than the previous implementation, due to replacing std::vector<_Cmpt> with a custom pimpl type that only needs a single pointer. The _M_type enumeration is also combined with the pimpl type, by using a tagged pointer, reducing sizeof(path) further still. Construction and modification of paths is now done more efficiently, by splitting the input into a stack-based buffer of string_view objects instead of a dynamically-allocated vector containing strings. Once the final size is known only a single allocation is needed to reserve space for it. The append and concat operations no longer require constructing temporary path objects, nor re-parsing the entire native pathname. This results in algorithmic improvements to path construction, and working with large paths is much faster. PR libstdc++/71044 * include/bits/fs_path.h (path::path(path&&)): Add noexcept when appropriate. Move _M_cmpts instead of reparsing the native pathname. (path::operator=(const path&)): Do not define as defaulted. (path::operator/=, path::append): Call _M_append. (path::concat): Call _M_concat.
