Figure.pygmtlogo: Set the region based on wordmark for easier design

[seisman]

Currently, the region is set to [-4, 4, -4, 4]. The issues are:

1. We need to use no_clip=True when adding the wordmark
2. We can't adding debugging lines (gridlines) for wordmarks, so we can't control the size of the wordmark accurately.

This PR does three things:

• sets the region based on wordmark, i.e., larger x-range for horizontal wordmark and larger y-range for vertical wordmark
• slightly modifies the code for adding debugging lines to ensure the debugging lines are plotted inside the visual logo only
• adds two baseline images for the logo design with horizontal/vertical wordmark. The orginal baseline image for a visual logo without a wordmark is no longer needed, because it's already covered by the two new baseline images.

Ideally, we should be able to remove the no_clip=True argument from the Figure.text call. But as you can see, the wordmark in the vertical version is slightly wider than the visual logo.

Edit: I've slightly decreased the font size for the vertical wordmark, and then remove the no_clip parameter from Figure.text.

Old version	New version

Please note that the design of wordmarks is still ongoing in PR #4627. So, this PR focuses on adding tests to make the wordmark design easier.
