Bugfix for variables in multiple groups

[peverwhee]

PR to address issue with variable intents across groups.

Description

• Current behavior for variables across groups: the intent for the first group is used as the "truth".
  • If variable "foo" is intent "out" in Group A and intent "in" in Group B, "foo" will be added to the variable dictionary used by the host as intent "out", which then the host assumes means that the framework will handle it
• Updated behavior for variables across groups: adjust the intent of the existing variable to "inout" if a conflict arises across groups (or suites)

User interface changes?: No

Testing:
test removed: N/A
unit tests: Updated capgen & ddt test - variable intents across suites also affected; PASS
system tests: all PASS
manual testing: Ran in CAM-SIMA

That looks like an easy fix :-) But pretty sure it took a while to decipher where things went wrong.
