tdf#160386: Add support for switch element

For now, only use language tag, meaning if
there is a file like in the unittest with

<text systemLanguage="en-us">Howdy!</text>
<text systemLanguage="en-gb">Wotcha!</text>
<text systemLanguage="en-au">G'day!</text>
<text systemLanguage="en">Hello!</text>

"Hello!" with be displayed in a en_AU system locale

This patch partially reverts 13a41e7a12598c7896d6dc8d34aba6af5b80b83c
"tdf#150124: do nothing when parent is of unkown type"
making 0dfd8288a87b58e503bb3a41be6137485fbf3f68
"ofz#60384 Direct-leak" no longer necessary
