userlandfs: use std::bitset for FSCapabilities

gcc 13 is confused by the custom bitset implementation, so use the C++
standard one instead.

However, this results in including the C++ <string> header in kernel
code. This doesn't work for gcc2, because of two problems:

- That header includes a declaration of atomic_add that doesn't match
the one in SupportsDefs.h (which can in some cases replace the function
with a #define for an inline version). Adjust the header to use the
be a problem because it creates a risk of circular inclusions.
Standard C++ headers shouldn't depend on BeAPI ones.
- It also leads to the inclusion of iostream which defined lock and
unlock functions in the global namespace. We don't want these, and they
are not part of the C++ standard, so just remove them.

Ideally we could use std::hash for the GetHashCode implementation, but
that doesn't work because it depends on an helper function that's in
libstdc++, and we can't link that from kernel add-ons.

Added interface constant for FUSE.

Some more work towards adjusting the UserlandFS to the current FS interface:
* Split the FSCapabilities bit mask into three bit masks for the FS, the
volume, and the vnodes, since we have three independent FS interface
structures, now. The latter is not supported in the kernel add-on, yet.
* Server:
- Temporarily removed some things from the build (the BeOS interface
and the cache implementations).
- Some WIP in HaikuKernelVolume and [haiku_]kernel_emu.{h,cpp}.
- Added HaikuKernelNode, which wraps fs_vnode for the client FS.
The server is still quite a bit away from being buildable again.

We analyze a client FS's capabilities -- i.e. which hooks it provides or
can be emulated -- and pass this info to the kernel add-on. Thus we can
avoid passing requests to the userland that can't be serviced anyway.
