efl_mono: Use architecture independent ECANCELED

Summary:
`efl_mono` was assuming ECANCELED as in Linux, which made some tests
fail.

`test_simple_futere_cancel` and `test_cancel_after_resolve` checks if
the returned error code is `ECANCELED` but `Eina.Error.ECANCELED` was
base on Linux `ECANCELED` which is diferent from OSX causing:
```
[ ERROR       ] AssertionException: /Users/lucas/expertise/efl1/src/tests/efl_mono/Promises.cs:138 (test_simple_future_cancel) Left hand side "Eina.Error(89)", right hand side "Eina.Error(125)"
at Test.AssertEquals[T](T lhs, T rhs, String msg, Int32 line, String file, String member) in /Users/lucas/expertise/efl1/src/tests/efl_mono/TestUtils.cs:line 73
at TestSuite.TestPromises.test_simple_future_cancel() in /Users/lucas/expertise/efl1/src/tests/efl_mono/Promises.cs:line 138
[        FAIL ] TestPromises.test_simple_future_cancel
```
```
[ ERROR       ] AssertionException: /Users/lucas/expertise/efl1/src/tests/efl_mono/Promises.cs:256 (test_cancel_after_resolve) Left hand side "Eina.Error(89)", right hand side "Eina.Error(125)"
at Test.AssertEquals[T](T lhs, T rhs, String msg, Int32 line, String file, String member) in /Users/lucas/expertise/efl1/src/tests/efl_mono/TestUtils.cs:line 73

[        FAIL ] TestPromises.test_cancel_after_resolve
```

And `iwraper.cs:WrapAssync` was only considering Linux `ECANCELED` thus causing
a rise of an `Efl.FutureException: Future failed` instead of the expected
`TaskCanceledException` making fail at `TestEoAsyncMethods.test_async_cancel`:
```
[ RUN         ] TestEoAsyncMethods.test_async_cancel
[ ERROR       ] AssertionException: Assertion failed: /Users/lucas/expertise/efl1/src/tests/efl_mono/EoPromises.cs:175 (test_async_cancel) AggregateException must have been TaskCanceledException

```

Depends on D12156

Test Plan:
Compare with master and note that with this diff all tests pass.
- Configure as especified by Enlightenment man page + `-Dbindigns=mono -Ddotnet=true`:
```
meson -Dsystemd=false -Dv4l2=false -Davahi=false -Deeze=false -Dx11=false -Dopengl=full -Dcocoa=true -Dnls=false -Demotion-loaders-disabler=gstreamer1,libvlc,xine -Decore-imf-loaders-disabler=scim,ibus -Dbindigns=cxx,mono -Ddotnet=true build
```
- Build normally
- Test `efl-mono-suite`
