Fixes #2093

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 test added for softButtonCapabilities.imageSupported = YES and displayCapabilities.graphicEnabled = NO, as well as visa-versa.

Core Tests

Tested that existing behavior continues to

Core version / branch / commit hash / module tested against: Sync 3.4 TDK (19353_DEVTEST)
HMI name / version / branch / commit hash / module tested against: Sync 3.4 TDK (19353_DEVTEST)

Summary

This PR works around a bug when connecting to Sync 2.0 head units that causes the app to attempt to upload soft button images that will never work. This wastes bandwidth and time.

The issues happens because Sync 2.0 doesn't support softButtonCapabilities, so the library assumes all capabilities are available. However, Sync 2.0 does report that all graphics are unsupported in RAIR.displayCapabilities.graphicSupported.

Update var graphicsEnabled -> isDynamicGraphicSupported, to align with the java suite PR.
I suggested the changes where the var is defined, the remaining changes should be noticeable when xcode flags the errors for using an unknown var
