Merge bitcoin/bitcoin#24104: fs: Make compatible with boost 1.78

dc5d6b0d47 fs: Make compatible with boost 1.78 (Andrew Chow)

Pull request description:

  Boost 1.78 removed `operator+` in a way that breaks our usage of it in a subclass. A [proposed workaround](https://github.com/boostorg/filesystem/issues/223#issuecomment-1000230207) for this is to cast the argument to `boost::filesystem::path`, and this is backwards compatible with older versions of boost.

  Additionally, it appears that `fs::canonical` no longer removes trailing slashes. This was causing a test to fail. The solution is to explicitly remove the trailing separator in the one place that `fs::canonical` is used.

  Lastly, `fs::create_directories` now has an error message saying `create_directories` instead of `create_directory`. This caused wallet_multiwallet.py to fail. The error message check has been updated to be able accept either string.

  Fixes #23846
