Use Calibri and Lucida Console, when it's possible, in place of sans-serif and monospaced (bug 1922063)

A recent change in Firefox induced too much difference between the text widths computed in using a Canvas
and the ones computed by the text layout engine when rendering the text layer. Consequently, the
text selection can be bad on Windows with some fonts like Arial or Consolas.
This patch is a workaround to try to use in first place some fonts which don't have the problem.
