Problem: Modifiers not simplified when timed out or using feedkeys() with
'n" flag.
Solution: Adjust how mapped flag and timeout are used. (closesvim/vim#10305)

Reverts commit 337b6179dfCloses#6716 at the expense of not being able to use a
multi-key 'pastetoggle' manually.
Multi-key 'pastetoggle' can still be used when inserting the entire
option into the typebuffer at once (though the use here is
questionable).
Also remove those tests to do with waiting for the completion of
'pastetoggle' and mention in the documentation that 'pastetoggle'
doesn't wait for timeout.
If we `set pastetoggle=abcde`, and manually type it, then `vgetorpeek()`
sees part of the option before it has all been inserted into the
typebuffer.
To signify this it sets `keylen = KEYLEN_PART_KEY`, but the condition
about whether to return the current key from `vgetorpeek()` only checks
for `keylen = KEYLEN_PART_MAP`.
Add a check for `KEYLEN_PART_KEY` to account for the `'pastetoggle'`
option.
