tdf#158658 sw: text formatting: try to make TabOverMargin more crazy

... to better match Word's formatting; this commit is not based on a
complete diagnosis of Word's compatibility-mode tab-in-margin
formatting disorders.

1. in SwTabPortion::PreFormat() allow a left aligned tab beyond the
width of the paragraph, like already done for TabOverSpacing

2. in SwTextFormatInfo::GetLineWidth() add some extra width to the
paragraph so text can be hidden in the right margin.
(it's very unclear what Word does here exactly, in one case it puts
339 additional "a" characters in the margin but then the 340th "a"
goes onto a new line...)

3. in SwTextFormatter::NewTabPortion() allow manual tab stops to be
positioned beyond the width of the paragraph, like already done
for TabOverSpacing

testTdf118672, testTdf120287b, testTdf120287c fail but the files,
converted to RTF, render in Word 2013 basically the same as in Writer
with this change.
