Arlo Breault 94c4d619a7 Add a checkbox to use the image caption as the alt text for galleries
The need for something like this was anticipated in
I2bf43c7e83283f43e047229eb53c244918fcbb0c.

As of version 2.5.0 of Parsoid's output, if alternate text is missing
for an image but a caption is present and image isn't displaying the
caption (ie. it isn't a thumb or frame), then the text content of the
caption will be set as the alt attribute.  Parsoid will then drop the
alt attribute when serializing if it matches the caption text, since
it's unnecessary.

However, if the caption is modified and the alt text isn't, the alt will
be serialized.  This is likely to be unexpected to editor.  They may
have missed that the both the caption and alt are populated in VE and
only edited one place.

Since all of the above is happening only for images where the caption
isn't visible, it doesn't appear to be a much used feature since, at
least for inline images, the experience of caption editing was already
less than optimal.

However, because of a quirk in how galleries are rendered in Parsoid,
this affects gallery caption editing, which is visible and presumably
used more often.  See T268250 for a discussion on an improved gallery
structure.  But for now, gallery images are effectively inline and set
the alternate text, thus subject to the above.

Here we add a checkbox so that the default is to ignore the alt if it's
the same as the caption.  And only make use of it if it differed
originally or was explicitly unchecked to modify.
