Text: table text takes the master's other-text style

PowerPoint for Mac lays out a table's text in the master's other-text
style (p:otherStyle), while shapes and text boxes take the presentation's
default text style (p:defaultTextStyle). A synthetic deck with an
otherStyle of 14 pt and a defaultTextStyle of 26 pt, exported as PDF,
draws a table cell at 14 pt and a shape's and a text box's text at 26 pt.
DeckCraft laid cells out through a stand-in shape that wasn't a table, so
they took the default text style: a deck whose two styles differ (18 and
20 pt) drew its table text 2 pt too large and wrapped its cells.

master_list_style sends text in a non-placeholder table to otherStyle,
and Shape::table_cell builds the stand-in every cell layout uses (drawing,
row heights, text placement, the caret and selection in a cell) as a
table. The table shape itself resolves the same way, so the formatting
state of a selected table reports the size its cells draw at.
