85150731b7 test: put unit back, but rename it to someVal 
It is the simple and more efficient.
We just set `someVal` with the first value of `vars`.
Recall that `vars` is never empty.

f64753c106 test: simplify ac_expr.lean 
We don't want to avoid proofs at `List.getIdx` and `Expr` when doing proofs by reflection.
The new encoding avoids that by using the fact that `vars` in
`Context` should never be empty.

To be honest, the best approach is still the old `unit`. We can just
rename it to `inhabitant` to make sure users don't assume it is the
unit of the AC operator. Then, we can just set it with the first element
of `vars` and avoid proofs at `denote`.

fix: UTF-8 file path support for lean on Windows 
* fix msys2 windows build so the windows apps support utf-8 file paths.

* use windres to compile default-manifest.o

* windres is in binutils.

* stop modifying default-manifest.o

* copy to stage0

* fix semicolon joining of lists in add_custom_target

* undo changes to stage0 as per CR feedback.

* fix makefile

* fix: revert cmakelists.txt COMMAND_EXPAND_LISTS  change

* fix: msys2 dependencies

* add unit test for decoding UTF-8 chars to prove "lean.exe" can read utf-8 encoded files where utf-8 is also used in the file name.

* fix: utf-8 test by using windows-2022

* fix: do we really need cmake 3.11 or will 3.10 do?

* nope, really does require cmake 11.
