Restore old functionaliy for some Quill toolbar classes

[MacDeveloper1]

Description

Today I have again spent time to make my project looks as it must. I do not do anything critical just restore the funcitonality of some toolbar classes as they were. You may consider this PR as a starting point for all other buttons which I didn't change. The only thing is required is change call of QuillToolbarIconButton in build methods of embed buttons, search button and maybe others. You may see what I did. I also restored old QuillToolbarSelectAlignmentButton and save it as QuillToolbarSelectTextAlignmentButton.

I need this modifications to make my project compiled and continue working. You may merge this PR or use it for understanding how to make package backward compatible. It will take less effors.

This issue can be solved without reverting, it's looks like the issue is caused by using the new Material 3 recommended widgets instead of the previous ones that work for Material 2 and 3, updating to 9.x.x require using Material 3 and the new widgets listed in Flutter 3.16 in additional to other changes.
