extend `anchor-has-content` and `heading-has-content` with custom directive support

[Mikrovolnovka]

Is your feature request related to a problem? Please describe.
In the example of valid options there is a list of success for e.g. anchor:

<a>Anchor Content!</a>
<a><TextWrapper /><a>
<a is="TextWrapper" />
<a v-text="msg" />
<a v-html="msg" />

We have custom directive v-some-directive which also adds some innerHTML content to tag and I would also have to add to the list of allowed directives.

Describe the solution you'd like
It would be great if we could configure these rules so we can add valid directives and/or attributes so eslint would see next expected results as valid:
Success:

<a>Anchor Content!</a>
<a><TextWrapper /><a>
<a is="TextWrapper" />
<a v-text="msg" />
<a v-html="msg" />
<a v-some-directive="msg" />

Describe alternatives you've considered
Not sure I have some alternatives.
