Fix RewriteITEBv to ensure rewrite to fixpoint (#2878)
`TheoryBVRewriter::RewriteITEBv()` is currently always returning the
status `REWRITE_DONE`. This can result in a situation where a rewritten
node can be rewritten again (which breaks the contract of our rewriter).
The unit test in this commit illustrates the issue. The commit fixes the
issue by returning `REWRITE_AGAIN` or `REWRITE_AGAIN_FULL` if a node
changed. `REWRITE_AGAIN_FULL` is needed if the resulting node may have a
child that is not a subterm of the original expression.
