Add tests for "Runtime Errors for Function Call Assignment Targets"

[rkirsling]

Add tests for normative PR https://github.com/tc39/ecma262/pull/3568, which adds Annex B section, "Runtime Errors for Function Call Assignment Targets".

Specifically:

1. Correct the name of src/assignment-target-type/callexpression-arguments.case to callexpression.case and mark it onlyStrict.
2. Add onlyStrict cases to language/expressions/assignmenttargettype/ for +=, ++, and for-in/of. Also add case for &&= which applies regardless of strict or sloppy.
3. Add noStrict cases to annexB/language/expressions/assignment for =, +=, ++, and for-in/of which check that:
   • a ReferenceError is thrown
   • the function is called, but its return value is not resolved to a primitive
   • (= and += only) the RHS is not evaluated

---

Note: All hosts have some work to do.

• V8: onlyStrict cases fail
• SM: "its return value is not resolved to a primitive" fails for ++ (but += is OK)
• JSC: ~~"the function is called" is never true~~ (WebKit/WebKit#44364)

@rkirsling You should have tests where the function is named async to cover the case where the cover grammar is used.

@michaelficarra Whoops, somehow missed your comment earlier. Updated now.
