Pull request description:
The main goal is to remove [deprecated](https://github.com/bitcoin/bitcoin/issues/32361) code (removed in C++26).
This PR employs Microsoft's modern [approach](https://learn.microsoft.com/en-us/windows/apps/design/globalizing/use-utf8-code-page) to handling UTF-8:
> Until recently, Windows has emphasized "Unicode" -W variants over -A APIs. However, recent releases have used the ANSI code page and -A APIs as a means to introduce UTF-8 support to apps. If the ANSI code page is configured for UTF-8, then -A APIs typically operate in UTF-8. This model has the benefit of supporting existing code built with -A APIs without any code changes.
TODO:
- [x] Handle application manifests properly when building with MSVC.
- [x] Bump the minimum supported Windows version to 1903 (May 2019 Update).
- [x] Remove all remaining use cases of the deprecated `std:wstring_convert`.
- The instance in `subprocess.h` will be addressed in a follow-up PR, as additional tests are likely needed.
- The usage in `common/system.cpp` is handled in https://github.com/bitcoin/bitcoin/pull/32566.
Resolves partially https://github.com/bitcoin/bitcoin/issues/32361.

These overloads were needed to allow passing `fs::path` objects directly to
libstdc++'s `fstream` constructors, but after the previous commit, there is no
longer any remaining code that does pass `fs::path` objects to `fstream`
constructors. Writing new code which does this is also discouraged because the
standard has been updated in https://wg21.link/lwg3430 to disallow it.
Dropping these also means its no longer possible to pass `fs::path` arguments
directly to `fstream::open` in libstdc++, which is somewhat unfortunate but not
a big loss because it is already not possible to pass them to the constructor.
So this commit updates `fstream::open` calls.
Additionally, this change required updates to src/bitcoin.cpp since it was
relying on the overloaded filename() method.
Try to make extra commands more obvious based on a suggestion from Sjors:
https://github.com/bitcoin/bitcoin/pull/31679#issuecomment-2922787970i
When `bitcoin` is invoked with no arguments, still show short help output, but
now explicitly state that more commands are available and `bitcoin help` will
list them.
Also:
- Get rid of -a/--all option. Just show all commands when `bitcoin help` or
`bitcoin --help` is used. It maybe a helpful to add an option like this if
more commands are added in the future, but right now there are not very many.
- Just show name of executable, not full path of executable in help output. This
can be a little easier to read if the path is long.
Intended to make bitcoin command line features more discoverable and allow
installing new multiprocess binaries in libexec/ instead of bin/ so they don't
cause confusion.
Idea and implementation of this were discussed in
