[Mobile] Fix regressions with wrapper props and font size customizati…

…on (#56985)

* Mobile - Hooks - Use createBlockListBlockFilter

* Mobile - Typography - Refactor the code to incorporate the latest changes from its web counterpart

* Mobile - BlockList: Apply editor.BlockListBlock filter to fix issue with missing block props, as well as refactoring the getEditWrapperProps logic to use the same approach as its web counterpart

* Mobile - Test helpers - Add more global styles data: font sizes and line height

* Mobile - Font Size Picker - Improvde the accessibility label for the Font Size selector

* Mobile - Paragraph tests - Add test for font size and line height customization

* Mobile - Safe guard from an undefined wrapperProps value

* Mobile - Fix having the default font sizes when there are theme font sizes available

* Mobile - Global styles context test - Remove default font sizes

* Mobile - Paragraph tests - Update tests to use modal helpers

* Mobile - Paragraph tests - Adds test to check if the available font sizes are the ones expected with no duplicates

* Update Changelog
