This completes the work that started in PR #33069, and fixes#32835.
There are probably two additional related changes that are needed to
make this more complete:
* Fix the code that composes the error message (see the first two
`FIXME`s in `callWithSpread3.ts`).
* Fix the code that checks the argument types (second two `FIXME`s).
* There is also an error in `genericRestParameters1.ts` which changed
but should not be an error in the first place. Added a `FIXME` there
too. (Probably will work if the previous iterm is done.)
In addition, `getEffectiveCallArguments` munges the arguments in case of
a spread in the last argument which might be better to avoid. (I think
that there are cases where it wouldn't work anyway, such as a spread of
an array followed by a spread of an empty array.)
