Add geometryPadding parameter for .camera Viewport

Nobody has claimed this yet.

## New Feature

<- Description of the feature being requested and any outcomes desired, an example use case, and any suggestions for solution ->
Similar to `.overview `**Viewport** we should have a `geometryPadding` parameter that applies padding to the map’s coordinate geometry. Currently, the only way to create an inset is by using the `.padding` modifier. The problem is that `.padding` shifts the entire rendered map, which—when using the Globe projection—results in the entire globe being visually offset. A dedicated `geometryPadding` argument would avoid this by padding only the coordinate space, not the rendered map.

## Why
<- 1-2 sentence description of why you're requesting this feature. What problem does it solve? Why is it valuable? ->
This is both a feature but also a bug in the current SDK. It would enable offsetting the map without offsetting the Globe projection for when wanting to fully zoom out

Start by locating the .camera Viewport and .overview Viewport APIs, then compare how their padding is represented and applied. Done means a geometryPadding parameter affects only coordinate geometry, allowing Globe projection insets without shifting the rendered map.
