Generated avatars as well as text file previews are rendered using the "core/fonts/NotoSans-Regular.ttf" font. The file was the standard hinted "NotoSans-Regular.ttf" file from https://www.google.com/get/noto/. However that file does not cover some non LGC (Latin, Greek, Cyrillic) scripts, like Arabic, Devanagari or Hebrew, to name a few. Markdown file previews also use "core/fonts/NotoSans-Bold.ttf", which is in the same situation as the regular one. Due to limitations in the TTF format it is not possible to provide a single file for each style that includes all Noto fonts. However, it is possible to add more scripts to the standard "NotoSans-Regular.ttf" and "NotoSans-Bold.ttf" files (although no CJK (Chinese, Japanese, Korean) glyph can be included due to the aforementioned limitations). This commit replaces the standard files with an extended version created using the Noto Tools. The build script (as well as a patch for the Noto Tools) is also included for reference and to be able to update the font files in the future if needed. Due to the additional scripts added the font files are now much larger, although this does not seem to increase the time spent rendering LGC scripts. Note that the file for the bold style still contains less scripts than the regular one, as not all scripts supported by Noto have a bold weight.

The command is meant to be used when the fonts used to render texts
("core/fonts/NotoSans-Regular.ttf" and "core/fonts/NotoSans-Bold.ttf")
are changed (for example, to add support for other scripts). The avatar
and text file previews will be removed, so they will be generated again
with the updated font when needed.
