Any C# file can be loaded as script and at load
time we don't yet know if it's actually meant to
be used as a script. As such, such an check can
result in a lot of false errors.

If the file is really meant to be used as a
script, an error would be printed later when
attempting to instantiate it any way.

Remove HQ2X and the `Image.expand_2x_hq2x()` method

Fixes #38778

As of Godot 3.0, HQ2X is no longer used to upscale the editor theme
and icons on hiDPI displays, which limited its effective uses.
HQ2X was also used to upscale the project theme when the "Use Hidpi"
project setting was enabled, but results were often less than ideal.
The new StyleBoxFlat and SVG support also make HQ2X less important
to have as a core feature.

This decreases binary sizes slightly (-150 KB on most platforms,
-212 KB on WebAssembly release).

This partially addresses #12419.

EditorDebuggerServer::register_protocol_handler must not be called before
editor initialization. Otherwise, if the editor is never initialized,
the added StringName will not be released until static destructors are
called (instead of being release during editor deinitialization).
