Toolbar button styling to reflect cursor position when running on desktops with keyboard to move caret.

[AtlasAutocode]

Description

Proposed changes make the toolbar buttons selection state reflect the styling as the cursor is moved. Using desktop (Windows) keyboard cursor keys to move the caret position (without selecting text).

• Fix inline style tracking: When cursor is moved into a region of bold, the bold style is correctly recognized and reflected in the toolbar status. Problem: When the cursor keys move the caret out of the bold region, the bold style is not cleared and cannot be removed.

• Fix: toggle_style_button failed to call default afterButtonPressed in base button settings. Constructor called options.afterButtonPressed rather than the class function afterButtonPressed that defaults to a call to QuillToolbarBaseButtonOptions.

• Fix: quill_icon_button build when isSelected did not call afterButtonPressed (expected same action as when not selected).

• Fix: QuillController _updateSelection removed param=source because not used; added new param insertNewline to recognize when a newline entered and maintain the correct inline style by correctly setting toggledStyle; updated replaceText to call _updateSelection for newline.

• Fix: document.dart collectStyle: Click at the start of a line (of bold text), user would expect the style to be the visible style of the line including inline styles. Also requires updating insert.dart PreserveInlineStylesRule to recognize if inserting text at start of line and use attributes from the first char on line

• Fix: color_button : Add afterPressed param to QuillToolbarIconButton

Suggestions

QuillController (public function) updateSelection also does not use the ChangeSource parameter.
ChangeSource enum does not appear to be used anywhere - is this deprecated or am I missing something?

I'm not so sure about the changes in the insert rule and the document file

I haven't made any changes to the base of the library (in the document, raw editor widget, the rules, etc...)

Can you revert all the unused comments like the ones in the example folder?
