[api-minor] Annotations - Adjust the font size in text field in considering the total width (bug 1721335)

- it aims to fix #14502 and bug 1721335;
 - Acrobat and Pdfium do the same;
 - it'll avoid to have truncated data when printed;
 - change the factor to compute font size in using field height: lineHeight = 1.35*fontSize
  - this is the value used by Acrobat.
 - in order to not have truncated strings on the bottom, add few basic metrics for standard fonts.
