Function 'getArgFromDecorator' need to be updated in vue3 & vue-class-component@8

[FangyuDu]

Env: vue3 + ts + vue-class-component

The problem
In vue-class-component@8, decorator Component will be renamed.
@Component will be renamed to @Options

decoratorIdenifier 'Options' need to be added in filter condition

<template lang="pug">
button.c-button: slot
</template>
<script lang="ts">
import { Options, Vue } from 'vue-class-component'
import { Prop } from 'vue-property-decorator'

@Options({})
export default class Button extends Vue {
  @Prop({ type: String, default:'primary' }) type!: string;
}
</script>
