bump crengine: ODT support, more typography languages (#6675)

Includes:
- Update German hyphenation patterns
- (Upstream) Adds ODT (ODF) format support
- TextLang, hyphenation: add Basque, Croatian, Esperanto,
  Estonian, Georgian, Latvian, Lithuanian, Macedonian,
  Occitan, Welsh; update Bulgarian, Irish, Portuguese,
  Slovak, Dutch, Norwegian, Spanish; update hyphen min
  for Czech, English, Greek; fix Romanian and Ukrainian
  pattern file names
- HyphMan: adds HyphMethod::getLeft/RightHyphenMin()
- epub.css: update HR default style
- fb2.css: keep <date> in main text left-aligned
- getRenderedWidths(): inline-block and table fixes
- CSS: avoid style hash mismatch when serializing content:''
- Tables: re-order row groups when necessary
- XML parsing: don't drop trailing text
- HTML parser: tweak implicit head/body insertion code
- Fix text search failure when blank at start or end

readertypography.lua: some cleanup by removing the first
table listing hyph dicts, and including their filenames
in the second table so we can build the first table
dynamically. Also fetch hyph left/right min limits from
crengine to not have to duplicate them here and keep them
in sync.
css_tweaks.lua: for in-page footnotes, switched from
"-cr-only-if: epub-document" to ": -fb2-document"
("not" FB2 documents), so these tweaks also work with
DocX and ODT footnotes.

Also included in base bump:
- KOPTContext: add comic panel detection function/additional
  leptonica declarations
- Forcibly disable docs when building giflib
