This PR fixes several issues related to the Mark formatting.

• It completes the missing functionality implementation to fully support the Mark tag.
• Adds MarkStringAttributeConverter which will handle toggling the format as well as returning the expected HTML format to Gutenberg, by removing the extra spaces. This was causing issues like history changes or showing the active style indicator when it shouldn't.
• Updates MarkFormatter to set the expected CSS attributes as well as adding a color param.
• Adds preprocessMarkForInsertion that will handle cases like auto-corrected strings, it will check if the new auto-corrected words need to have the Mark representation along with adjustAttributesForMark.
• It also fixes toggleMark by allowing passing a color param and to be able to change colors while editing a Mark formatting or resetting the existing format.

Hey @twstokes 👋 I was wondering if you could help me out with a review for this PR since part of it uses the same code you added for the Heading fix for the highlighting text feature.

No worries if you can't, let me know either way. Thanks! 🙇
