Ignacio Etcheverry ced77b1e9b C#: Switch games to MSBuild Sdks and .NET Standard
Godot.NET.Sdk
-------------

Godot uses its own custom MSBuild Sdk for game
projects. This new Sdk adds its own functionality
on top of 'Microsoft.NET.Sdk'.

The new Sdk is resolved from the NuGet package.

All the default boilerplate was moved from game
projects to the Sdk. The default csproj for
game project can now be as simple as:

```
<Project Sdk="Godot.NET.Sdk/4.0.0-dev2">
  <PropertyGroup>
    <TargetFramework>netstandard2.1</TargetFramework>
  </PropertyGroup>
</Project>
```

Source files are included by automatically so
Godot no longer needs to keep the csproj in sync
when creating new source files.

Define constants
----------------

Godot defines a list of constants for conditional
compilation. When exporting games, this list also
included engine 'features' and platform 'bits'.
There were a few problems with that:

- The 'features' constants were only defined when
  exporting games. Not when building the game for
  running in the editor player.
- If the project was built externally by an IDE,
  the constants wouldn't be defined at all.

The new Sdk assigns default values to these
constants when not built from the Godot editor,
i.e.: when built from an IDE or from the command
line. The default define constants are determined
from the system MSBuild is running on.

However, it's not possible for MSBuild to
determine the set of supported engine features.
It's also not possible to determine if a project
is being built to run on a 32-bit or 64-bit
Godot executable.

As such the 'features' and 'bits' constants had
to be removed.
The benefit of checking those at compile time
was questionable, and they can still be checked
at runtime.

The new list of define constants includes:

- GODOT
- GODOT_<PLATFORM>
  Defaults to the platform MSBuild is running on.
- GODOT_<PC/MOBILE/WEB>
- TOOLS
  When building with the 'Debug' configuration
  (editor and editor player).
- GODOT_REAL_T_IS_DOUBLE
  Not defined by default unless $(GodotRealTIsDouble)
  is overriden to be 'true'.

.NET Standard
-------------

The target framework of game projects was changed
to 'netstandard2.1'.

<!--
We import a props file with auto-generated includes. This works well with Rider.
However, Visual Studio and MonoDevelop won't list them in the solution explorer.
We can't use wildcards as there may be undesired old files still hanging around.
Fortunately code completion, go to definition and such still work.
