200a38e20c feat: improve letIdLhs parser
The extra space is only really needed to distinguish an array update (NIY)
```
let x[i] := ...
```
from a declaration taking an instance argument
```
let f [Monad m] := ...
```

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.

9e980b2a78 fix: bug at decAux?
We are getting a few "stuck at universe constraint" errors after the
fix. We may need to add some kind of approximation in the future.

c2d33a1a58 fix: bug at addSmartUnfoldingDef
The approach using `matcherBelowDep : NameSet` was not correct because
we "reuse" matcher-declarations. For example, in the definition
```
def f : Nat → Bool
  | 0 => true
  | n + 1 => (match n with
    | 0 => true
    | _ + 1 => true) && f n
```
we have to `match`-expressions but they can be compiled the same
matcher `f.match_1`. Thus, the set `matcherBelowDep` would contain
`f.match_1` since the first occurence refined the `Nat.below` argument
at `mkBRecOn`. Thus, `addSmartUnfoldingDef` was incorrectly assuming the second
`match` was refined too.

We fixed this issue by simulating `mkBRecOn` behavior.
