The code completion might occur inside an attriubte that isn’t part of the AST because it’s missing a `VarDecl` that it could be attached to. In these cases, record the `CustomAttr` and type check it standalone, pretending it was part of a `DeclContext`. This also fixes a few issues where code completion previously wouldn’t find the attribute constructor call and thus wasn’t providing code completion inside the property wrapper. rdar://92842803
