fdo#53399 Word count is inconsistent and wrong with non-breaking space

This change replaces lcl_IsSkippableWhitespace with a call to ICU's u_isspace, which covers all 
Unicode separators. It also updates and fixes one of the SwScanner unit tests.

Bug details:
SwScanner::NextWord skips whitespace before calling into ICU's BreakIterator. The function used to 
identify whitespace (lcl_IsSkippableWhitespace) doesn't cover the full category of Unicode 
separators (code [Zs], 18 in total. See: 
http://www.fileformat.info/info/unicode/category/Zs/index.htm).

Since 0xA0 (no-break space) is not identified as whitespace and not skipped, we end up calling ICU 
starting at the position 0xA0, asking it to get us the boundary of the next word forward. ICU sees 
that it's called at the end of a word, and reverses the query direction to backward, and returns 
the word before. This causes NextWord to think we've hit the end of the string and call it a day, 
terminating word count for the rest of the line.
