tdf#92036: sw: fix idle spelling loop

There is a sort of intentional infinite loop in the idle spell checking
handler: while the user is typing a word, it should not be marked as
invalid yet, in order not to annoy them with red underlines.

So the word where the cursor is positioned always remained dirty, unless
you happen to have a grammar checker enabled, which clears the
paragraph's dirty flag from a separate thread.

To avoid the infinite loop, add another spell checking state "PENDING"
which is the same as dirty except that it should cancel the idle spell
checking.

The idle spell checking will run again when the user does the next
editing operation.  Notably this means if the user just moves the cursor
out of the wrongly spelled word, it won't be underlined yet, but that
appears a minor issue, and checking when the cursor leaves the word
appears too hard to implement.
