refactor: linkcheck: Remove next_check from Hyperlink object

To separate hyperlink itself and checking (intermediate) state, this
removes `next_check` attribute from Hyperlink object and add a new
named-tuple `CheckRequest`.  It was rejected idea on implementing
rate-limiting first (see #8467).  But it's better way to separate
large builder module into small components and make whole of linkcheck
builder simple.

After this change, `Hyperlink` object represents a hyperlink on the
document.  It has a URI and location info (docname and lineno).
