v8's `_resolve_php_member_calls` (#3872) binds scoped `Class::method()` calls
but leaves instance `$g->method()` calls unresolved. This adds the instance
tier beside it: a per-file receiver type table (`_php_receiver_type_table`
over typed properties, promoted constructor params, typed params and `new`
bindings) names the receiver's class, and the shared resolver takes the single
PHP declaration of that class and emits the `calls` edge, INFERRED.
The declaration index is gated to the PHP interop family: the index is
corpus-wide, so a same-named class in another language would both answer the
receiver and hide that no PHP file declares it. A receiver the table cannot
type to one class — untyped, union, longer chain — stays unresolved.
