The added `#` prevents clang-format from misinterpreting the meaning
of this statement and thus messing up the formatting of the next
lines up until the first `layout` statement.

Similarly, a semicolon is now enforced on `versions` defines to
prevent clang-format from messing up formatting and putting them
all on a single line. Note: In its current state the code will
ignore chained statements on a single line separated by a semicolon.

Also removed some extraneous lines missed in previous style changes
or added by mistake with said changes (e.g. after uniform definitions
that clang-format messes up somewhat too, but we live with it).

Add more missing node icons

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.

websocket: Fix crash at exit when not running the editor

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).
