[ARROW-14720] [Doc][R] Link to the documented threading model

• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Component/s: Documentation, R
• External issue URL: https://issues.apache.org/jira/browse/ARROW-14702

Description

Linked issues:

• https://issues.apache.org/jira/browse/ARROW-14663 - discussion on exposing the number of threads to the read and write CSV functionality in R.
• https://issues.apache.org/jira/browse/ARROW-14702 - issue on improving the C++ documentation on how Arrow does multithreading. We should link to these docs from the R side. 

We should probably add details to the read_csv_arrow documentation linking to cpu_count()/set_cpu_count as the way to control multi-threading. And possibly refine the documentation about the others (or set them to keywords-internal if we don't expect users to need to or want to set them).
