REPORT-44961 【10.0.12冒烟】附件模板打开设计器卡死，且布局发生变化

【问题原因】带有数据字典的表单控件，在选中的时候会去连接获取字段信息，当系统中有同名数据连接但是无法连接到数据库的时候，会发生假死。如果没有这个数据连接的名字，那么会直接报错不会假死。主要还是这个数据字典获取数据的操作是耗时操作，不应该在UI线程进行耗时操作。
【改动思路】主要分为两部分，第一是将原本的tdChange()方法中的耗时操作放到SwingWorker中的工作线程中，这样的话即使后台数据连接失败，设计器也不会一直阻塞直到重连超时；第二是应产品的要求，将选中控件就会去请求连接并获取属于当前控件的列名这部分逻辑，修改为用户点击右侧面板中的数据字典旁边的button的时候才会去请求连接，并更换当前数据字典中的列名
