Rearrange editor/naming/* project settings

[dalexeev]

1. Renamed the following project settings:

Before	After
editor/scene/scene_naming	editor/naming/scene_name_casing
editor/node_naming/name_num_separator	editor/naming/node_name_num_separator
editor/node_naming/name_casing	editor/naming/node_name_casing

2. The following editor settings replaced with project settings:

Before	After
interface/editors/default_signal_callback_name	editor/naming/default_signal_callback_name
interface/editors/default_signal_callback_to_self_name	editor/naming/default_signal_callback_to_self_name

Notes:

1. The project settings from the editor section should be moved to Editor Settings, but with the ability to override them for the project.

2. The setting editor/naming/scene_name_casing may need to be changed to editor/naming/file_name_casing (not only scene files should use this setting, but other resource types as well). See #57768.

3. I found that doc generation does not work for all project settings. It depends on the file where the setting is defined with GLOBAL_DEF:

• core/config/project_settings.cpp - ok
• editor/editor_file_system.cpp - error
• editor/editor_node.cpp - error
• editor/export/editor_export_plugin.cpp - error
• editor/plugins/version_control_editor_plugin.cpp - error
• scene/main/node.cpp - ok
• servers/movie_writer/movie_writer.cpp - ok

1. The project settings from the editor section should be moved to Editor Settings, but with the ability to override them for the project.

This will be possible after #69012

3. I found that doc generation does not work for all project settings. It depends on the file where the setting is defined with GLOBAL_DEF:

Ideally we should move all setting definitions to one place. See godotengine/godot-proposals#4771
