Remove ToolButton in favor of Button

Fixes: #39647

ToolButton has no redeeming differences with Button;
it's just a Button with the Flat property enabled by default.
Removing it avoids some confusion when creating GUIs.

Existing ToolButtons will be converted to Buttons, but the Flat
property won't be enabled automatically.

This closes https://github.com/godotengine/godot-proposals/issues/1081.

Increase the default DirectionalLight3D and OmniLight3D shadow biases

Implemented global const array to shaders

Export: Rename 'Windows Universal' to 'UWP'

[mono] Implement generics GetNodesInGroup

Added Texture2DArray support to visual shaders

Autofilled path gets set properly on animation subresources saving

It's otherwise too easy to be confused between 'Windows Desktop' (Win32)
and 'Windows Universal' (UWP).

[macOS] Command-backspace in line edit

Mono: Always define options in main.cpp to keep them in docs

Option in RichTextLabel for height to fit content

Rename "Identifier" to "Bundle Identifier" in macOS/iOS export presets

"Bundle Identifier" is more well-understood among macOS and iOS
developers and is less ambiguous.

This is a slight breaking change as export presets will need to be
updated to account for this change.

See https://github.com/godotengine/godot-docs/pull/3295.

Dont slice 64-bit integers marshaled to mono in dynamic contexts

Make command-backspace in line edit work like other macOS applications.

If there is a selection, command-backspace deletes the selection.

If there isn't a selection, command-backspace deletes from the cursor to the beginning of the line edit.

This addresses part of godotengine/godot#23548

Otherwise generating docs with non-Mono builds removes them,
which is not so convenient for the documentation work.

Ensures no error is issued when attempting to preview a resource that
may be scaled down to <1 pixel when resizing to fit the thumbnail.
