This PR adds missing implementation for the Mark formatting style.

• Adds a new MarkPlugin that will handle adding the needed CSS attributes.
• Updates the MarkSpan to receive a color param and to set it as the current color.
• Removes applyMarkInlineStyle in favor of applyAfterMarkInlineStyle which will handle if the color changes while editing a Mark span.

Test

Please follow the testing instructions in this PR's description.

This shouldn't affect other Aztec functionalities.

Make sure strings will be translated:

• [ ] If there are new strings that have to be translated, I have added them to the client's strings.xml as a part of the integration PR.

Hey there @antonis 👋

I was wondering if you would be able to help me out with a PR review 😄, I've updated the Highlight color implementation so it fixes some issues for this feature since we first partially implemented it in https://github.com/wordpress-mobile/AztecEditor-Android/pull/943

A lot of testing has been already done in https://github.com/WordPress/gutenberg/pull/57650 so I was wondering if you'd have some time to check the native code for the Aztec side. Let me know if you could take a look! Thank you!
