doc: net: Fix .rst rendering of net_cachelines pages

The doc pages under /networking/net_cachelines are unreadable because
they lack .rst formatting for the tabular text.

Add simple table markup and tidy up the table contents:

- remove dashes that represent empty cells because they render
  as bullets and are not needed
- replace 'struct_*' with 'struct *' in the first column so that
  sphinx can render links for any structs that appear in the docs
