  Log Message:
  -----------
  Crash when using `shape-outside: shape(...)`
https://bugs.webkit.org/show_bug.cgi?id=308649

Reviewed by Simon Fraser.

Extends the list of rejected <basic-shape> functions for `shape-outside` to also
include `shape()`.

Also adds style building time check so that any non-parser code paths that 
might try
to construct a `shape-outside` property value don't succeed.
