[joeljfischer]

Fixes #2047

Risk

This PR makes no API changes.

Testing Plan

• I have verified that I have not introduced new warnings in this PR (or explain why below)
• I have run the unit tests with this PR
• I have tested this PR against Core and verified behavior (if applicable, if not applicable, explain why below).

Unit Tests

Unit tests added to check file upload and RPC creation on those RPC versions without the image field

Core Tests

Tested creating a menu cell w/ subcells with an image. Note, Manticore is v7.1.0 but does not support the AddSubmenu image field, so submenu images will currently not show up.

Core version / branch / commit hash / module tested against: Core v8.0.0-RC
HMI name / version / branch / commit hash / module tested against: Generic HMI v0.11.0-RC

Summary

This PR makes two changes:

1. It will now add the AddSubmenu (menu cell w/ subcells) primary image on RPC connections >= 5.0 and < 7.0 because we don't have an image field name that corresponds to that image support.
2. It will now only upload menu cell images that are supported by the current window capability, which should be the same at all times.

Changelog

Bug Fixes

• Fixes uploading unnecessary menu cell images
