Include adb resize command

- [x] I have checked that a similar [feature request](https://github.com/Genymobile/scrcpy/issues?q=is%3Aopen+is%3Aissue+label%3A%22feature+request%22) does not already exist.

**Is your feature request related to a problem? Please describe.**
This may be considered a workaround for #886

**Describe the solution you'd like**
Include the ability to use the "adb shell wm size" command as a cli option (maybe "--size")
This helps devices that render at a non-standard screen resolution (eg Samsung Galaxy S10 renders at 2280x1080) present a standard resolution (1920x1080) onto a computer screen.

Start by tracing how scrcpy defines CLI options and invokes adb shell commands, then review issue #886 for context. Done means a CLI option can request a target size through “adb shell wm size” and the resulting behavior is verified by the relevant project checks.
