Reduce no format cases

[Enter-tainer]

Currently typstyle gives up formatting when:

1. @typstype off
2. When there are block comment child, gives up formatting the whole node. Why: We currently cannot handle block comment in all places
3. Multiline raw with single backtick. Why: it is white space dependent
4. When a child contains # in math mode, gives up formatting the whole node. Why: hash can appear anywhere, we havent handle it well.
5. Args in math mode. Why: it works very different. like 2d args, trailing commas
