[2.6] Remove controller specific role definitions (#7002)

Remove Controller specific roles

Removes
- Controller Organization Admin
- Controller Organization Member
- Controller Team Admin
- Controller Team Member
- Controller System Auditor

Going forward the platform role definitions
will be used, e.g. Organization Member

The migration will take care of any assignments
with those controller specific roles and use
the platform roles instead.
