bump crengine: monospace and fallback fonts tweaks (#1503)

Includes:
- Text: fix possible overflow with "white-space: pre"
- Fonts: getFontFileNameAndFaceIndex(): return family type
- Fonts: account for _bias in Font hash
- epub.css, fb2.css: remove hardcoded monospace font names
- Fonts: allow scaling monospace fonts
- Fonts: allow adjusting fallback font sizes to x-height
- HTML parser: trust xml encoding before html charset

cre.cpp: make setAsPreferredFontWithBias() a global
function (as it is not a per-document setting)
