Global styles revisions: update private methods to protected

[ramonjd]

This PR should only be merged if the corresponding Core patch makes it into 6.3.

Otherwise I'll have to prep the changes for 6.4 :)

What?

Updates the private vars and methods in the Global styles revisions rest API controller to be protected.

Core backport PR: WordPress/wordpress-develop#4867

Why?

So class entities that inherit from the base can use them, and we can iterate on 6.3 features without having to copy over private methods to new classes all the time.

Testing Instructions

All tests should pass.
There is no functional change, only changes 2 vars and 1 method to protected.
