Previously we had a placeholder solution called 'Managed' to benefit from tooling while editing the a part of the C# API. Later the bindings generator would create the final 'GodotSharp' solution including these C# files as well as the auto-generated C# API. Now we replaced the 'Managed' solution with the final 'GodotSharp' solution which is no longer auto-generated, and the bindings generator only takes care of the auto-generated C# API. This has the following benefits: - It's less confusing as there will no longer be two versions of the same file (the original and a generated copy of it). Now there's only one. - We no longer need placeholder for auto-generated API classes, like Node or Resource. We used them for benefiting from tooling. Now we can just use the auto-generated API itself. - Simplifies the build system and bindings generator. Removed lot of code that is not needed anymore. Also added a post-build target to the GodotTools project to copy the output to the data dir. This makes it easy to iterate when doing changes to GodotTools, as SCons doesn't have to be executed anymore just to copy these new files.
