tdf#160984 sw continuous endnotes: fix the endnote container's top marginHEADmaster

Comparing the Word vs Writer output for the bugdoc, the vertical
position of the endnote text is not correct: the y pos should be larger
than it is, see the red reference at e.g.
<https://bug-attachments.documentfoundation.org/attachment.cgi?id=194265>.

Seems this is caused by the different height of the rectangle around the
endnote separator: the top margin is 124 twips in Writer, which is a
hardcoded default from the SwPageFootnoteInfo ctor, while Word has this
separator as a special character, inside a paragraph, which inherits the
height of the default paragraph style.

Fix the problem by extending sw::FootnoteSeparatorHeight() to also work
from RES_POOLCOLL_STANDARD in the Word compat case. Note that it's not
enough to take the font size (11pt in this case) from the paragraph
style, we want to work with the real font, which knows the spacing
between lines (15% in this case). SwFont::GetHeight() has this logic,
it's also what e.g. SwTextFrame::FormatEmpty() uses.

Note that footnotes have the same problem, but given that they grow from
the bottom of the page, the text position was correct, even if the
separator height is incorrect. Also, the separator line itself is not
changed in this commit, we just make sure that the height is OK, so text
below the line has the correct position.
