This builds upon https://github.com/godotengine/godot/pull/38625 and improves the file name format as mentioned in https://github.com/godotengine/godot/pull/38189#issuecomment-626585363

The resulting file stored has the name `godot.windows.opt.tools.64-$(VERSION_HASH).zip` where `VERSION_HASH` is obtained from `it rev-parse --short=9 HEAD` , the zip file contains the built exe file.

thirdparty: Cleanup after #38386, document provenance and copyright

Also renamed `delaunay.h` to `delaunay_2d.h` to match the class name.

New GPU lightmapper

DisplayServerJavaScript, improvements to HTML5 build (still dummy renderer).

Use a different icon for the debugger tab with both warnings and errors

Rename the Clear Script editor action to Detach Script

Tweak the editor log selection color to match the current editor theme

Store build as artifact in appveyor

Input: Readd 'Default Android Gamepad' magic binding

Using the common behaviour when use command+shift on text line for osx

Removed by mistake in #38292 like the Windows `__XINPUT_DEVICE__`,
this magic binding is referenced directly in our code.

Fix VisibilityEnabler2D behavior on start

* On press left+command+shift or right+command+shift it should behave like shift+home or shift+end and select the text
* Using home and end events as reference

Fix inherited C# scene not inheriting parent's fields

C#: Support for building with the dotnet CLI

By adding a reference to the 'Microsoft.NETFramework.ReferenceAssemblies' nuget
package, we can build projects targeting .NET Framework with the dotnet CLI.
By referencing this package we also don't need to install Mono on Linux/macOS
or .NET Framework on Windows, as the assemblies are taken from the package.

Implement CSharpScript::inherits_script

-Added LocalVector (needed it)
-Added stb_rect_pack (It's pretty cool, we could probably use it for other stuff too)
-Fixes and changes all around the place
-Added library for 128 bits fixed point (required for Delaunay3D)

When a child scene inherits a parent scene with a C# root node, the
parent scene's export variables appear to assume values set in the
parent scene, in the child scene's Inspector. However, when the child
scene is played, the parent scene's export variables assume default
values.
When a node is created, it inherits its parent C# script's fields from
the map CSharpScriptInstance::script->member_info. However this map was
not initialized outside the editor, and this commit ensured it is. This
fixes issues #36480 and #37581.

Move copyToFS into utils.js library included with '--pre-js'.

Add missing semicolumns in engine.js
Add optional extra args to JS Engine.startGame
Remove loader.js, explicit noExitRuntime.
Also add onExit callback (undocumented in emscripten)

GDScript: Add join method on String

This reverts commit ec7b4811.

This was wrong, `d` is not a distance but the `d` constant in the
parametric equation `ax + by + cz = d` describing the plane.

This overrides the default blue color.

Style: clang-format: Disable if statements and case labels on single line

7z is already available in path in appveyor
zip the build .exe files and store them ( appveyor retains for ~6 months)

Switch to nuget Microsoft.Build and rewrite GodotTools messasing protocol

Part of #33027.

Part of #33027, also discussed in #29848.

Enforcing the use of brackets even on single line statements would be
preferred, but `clang-format` doesn't have this functionality yet.

Fix: saving gdscript with cyclic inheritance crash the editor

Allow using integer vectors for iteration and make range() use them

Fix: more clearer unexpected statement end error messages
