Compilation error: call to 'abs' is ambiguous

### Godot version

4.2

### godot-cpp version

4.2

### System information

Mac os 10.15

### Issue description

i am trying to build the godot-cpp library:
`scons platform=macos arch=x86_64 generate_bindings=yes`
and I get many such errors:
```
include/godot_cpp/core/math.hpp:569:9: error: call to 'abs' is ambiguous
return std::abs(x);
^~~~~~~~
```

I am using clang 11.0.3 and I see scons is indeed passing the std=c++17 flag which should be compilable via my clang version.

### Steps to reproduce

`scons platform=macos arch=x86_64 generate_bindings=yes` from the project directory.

### Minimal reproduction project

Using either the master of 4.2 branch of the project on a macos 10.15.7 (intel chip).
