Replace ButtonGroup usage with ToggleGroupControl

[mirka]

Part of #65338

All of our remaining usage of the ButtonGroup component is visually outdated as a segmented control and often inaccessibly implemented. We should correct this by replacing them with ToggleGroupControl.

Thank You,

@mirka I would like to work on the packages/block-editor/src/hooks/layout.js part of this issue. I am unsure of what component in the Editor LayoutTypeSwitcher is affecting so I have been unable to test that my change has not broken anything. I thought it might be the type size selector. See screenshot.

@spadeshoe Good question! I don't think this code path is actually reached in any of our core blocks. So you can force the condition like this:

diff --git a/packages/block-editor/src/hooks/layout.js b/packages/block-editor/src/hooks/layout.js
index 22d916d7b7..7a349ceb0b 100644

                        </>
                    ) }

-                   { ! inherit && allowSwitching && (
+                   { true && (
                        <LayoutTypeSwitcher
                            type={ blockLayoutType }
                            onChange={ onChangeType }

Then insert a Grid block, for example. And you'll see this:

Thanks @mirka The conditional trick worked and I was able to test the update. I created the PR for the change: https://github.com/WordPress/gutenberg/pull/65498

@jeryj and I had done some digging Tuesday and discovered what you did, that this code is no longer used in core blocks. I have a branch that removes this code all together. I'm not sure what the protocol is for removing "deprecated" code, if it should be removed at all for backwards compatibility.

@spadeshoe Thanks for the PR, we'll get it reviewed shortly!

Although it isn't used in any of the blocks in core, it's still a supported block API so we'll need to keep it 👍
