Consider adding Samsung devices into Preview

### Description

User of the Google Web Stories plugin have flagged that Samsung devices will render Web Stories differently than anticipated. Please consider being able to add current Samsung devices into the available device selection options in Preview, this would be helpful in understanding how these devices will render content uniquely.

### Alternatives Considered

There is no way to preview Samsung device output prior to publishing

### Additional Context

Samsung currently has almost a 30% market share worldwide ([source](https://gs.statcounter.com/vendor-market-share/mobile))

Start by tracing the Preview device-selection entry point and reviewing the existing device options. Determine which current Samsung devices are in scope, then add them and verify that they can be selected for Web Stories preview. The issue names no files or tests, so repository search will be needed to identify the relevant entry points and validation.
