What if `org-export--annotate-info' could be made async?

What about

It would be better to provide a command.
C-c C-c is too dramatic - it will reset much more than just preview
cache. (Like org-element-cache).
Or better add a new prefix arg to org-latex-preview that will force
re-generation.
Further, as discussed in the DM, we may need to consider that equation
preview may depend on latex export settings:
1. preview might be generic, utilizing "average" common latex preamble
2. preview might try to conform to latex export settings according to
full document export
3. preview might use a different latex preamble when the current subtree
will not actually be exported - like in commented subtrees. In
particular, it matters for equation numbering
4. preview might try to generate preamble according to subtree export
settings - some Org workflows involve multiple documents in one Org
file, exported separately via subtree export.
