Add features to typst base template (take 2).

New template variables supported: `thanks`, `abstract-title`, `linestretch`, `mathfont`, 
`codefont`, `linkcolor`, `filecolor`, `citecolor`.

Closes #9956, #11076.

(This is a new version of f000fa168bd122fee6e67f5a67bdd6d42d173261 which
was reverted.)
