1、新增流程定义，需要可以选择流程分类，同时带出应用类型，以便做相应的逻辑处理

2、ElementBaseInfo.vue 这个文件进行修改

<template>
  <div class="panel-tab__content">
    <el-form size="small" label-width="90px" @submit.prevent>
      <el-form-item label="ID">
        <el-input
          v-model="elementBaseInfo.id"
          :disabled="idEditDisabled || elementBaseInfo.$type === 'bpmn:Process'"
          clearable
          @change="updateBaseInfo('id')"
        />
      </el-form-item>
      <el-form-item label="名称">
        <el-input v-model="elementBaseInfo.name" clearable @change="updateBaseInfo('name')" />
      </el-form-item>
      <!--流程的基础属性-->
      <template v-if="elementBaseInfo.$type === 'bpmn:Process'">
        <el-form-item label="流程分类">
         <el-select v-model="elementBaseInfo.processType" @change="changeAppType">
