The fs.* files are already part of the libbitcoin_util library. With the
introduction of the fs_helpers.* it makes sense to move fs.* into the
util/ directory as well.
This is an extraction of filesystem related functions from util/system
into their own utility file.
The background of this commit is an ongoing effort to decouple the
libbitcoinkernel library from the ArgsManager defined in system.h.
Moving these functions out of system.h allows including them from a
separate source file without including the ArgsManager definitions from
system.h.
Call fs::u8path to convert some UTF-8 string literals to paths, instead
of relying on implicit conversions. The implicit conversions incorrectly
decode const char* paths using the current windows codepage, instead of
treating them as UTF-8. This could cause test failures depending what
environment windows tests are run in.

Warning: Replacing fs::system_complete calls with fs::absolute calls
in this commit may cause minor changes in behaviour because fs::absolute
no longer strips trailing slashes; however these changes are believed to
be safe.

There is no change in behavior. This just helps prepare for the
transition from the boost::filesystem to the std::filesystem path
implementation.

This adds better test coverage and will make it easier in #20744 to remove our dependency on the two-argument boost::filesystem::absolute() function which does not have a direct equivalent in C++17.
