Improve `require-g-image-src`

[hacknug]

Please write rule name what you want to improve: require-g-image-src

How are the rules improved?

Vue accepts passing an object directly to v-bind. It would be cool to support it besides passing props directly.

Provide 2-3 code examples that this rule should warn about:

// This should be accepted
<g-image v-bind="{ src: '' }" />

// This should be accepted or give a warning
<g-image v-bind="computed" />
<g-image v-bind="method(something)" />

// This should give an error
<g-image v-bind="{}" />

Additional context
I'm not sure if you could check the returned object from computed properties and methods. If that's possible that should be accepted as mentioned on comment.
