xmloff: ODF import/export for style:overflow-behavior "clip"

Adds initial support for style:overflow-behavior

According to OpenDocument-v1.3-part3 style:overflow-behavior can take
values of:
- "clip"
- "auto-create-new-frame"

This patch doesn't properly implement support "auto-create-new-frame",
only "clip".

If "clip" is set, TextClipVerticalOverflow is set to true, causing the
vertical overflowing text to be clipped.

"auto-create-new-frame" is treated the same as omitting the
style:overflow-behavior attribute, setting TextClipVerticalOverflow to
false.
