icon-text-fit should work with text-variable-anchor

[tristen]

Expected Behavior

When using these properties on a layer:

{
  'text-variable-anchor': ['left', 'top', 'right', 'bottom'],
  'text-justify': 'auto',
  'icon-text-fit': 'width'
}

I would expect both the icon that's been fitted under the label and the label to be variably placed.

Actual Behavior

Here's a label using a icon-text-fit background

Without text-variable-anchor	With text-variable-anchor

@asheemmamoowala yes, it is a bug, we need to offset an icon together with a text. Also, would be nice to document that in a spec as well.

@alexshalamov, would be nice to document in the spec now that this property doesn't work with icon-text-fit, or to document that it does after we close this issue?

[alexshalamov]

@chloekraw please disregard my comment, after checking the spec, I think it should be clear how icon-text-fit and variable anchors work together, e.g., icon would be shifted together with the text.

@ansis could you please take a look at gl-native fix in mapbox/mapbox-gl-native@19a49a5

Also, I had to fix it for combination of text-writing-mode with icon-text-fit.

[chloekraw]

@alexshalamov thanks for the investigation and proposed fix. per chat, I'm tracking that your next steps here are to split those commits out into a separate PR on GL-Native and to open a PR with render tests on GL-JS.
