[jumbo] Compile fix, one too many BstrToUTF8, rename BstrToPrettyUTF8

https://chromium-review.googlesource.com/c/chromium/src/+/1474976
introduced a BstrToUTF8 which in jumbo builds collided with an
existing (but different) BstrToUTF and broke Windows builds.

This renames one of the conversions to "BstrToPrettyUTF8" since it
not only converts but also makes the string readable for logs.

If the methods had been indentical it would have been suitable
to move them to
content/browser/accessibility/accessibility_tree_formatter_utils_win.cc
I think.
