Move one emulator and IOC test to a support directory

[DominicOram]

As a support person I would like to be able to specify in the IOC test framework where my emulator and test are. Currently they're in a central location but as of #6131 we want to move them around. I would then like to put the emulator and tests into the support directory and be able to run "make ioctests" from this directory to run the test.

Acceptance Criteria

• The emulator and test paths can be specified when running the IOC test framework
• A simple IOC has the tests and emulator moved into it's support directory (preserving history)
• Running "make ioctests" in this directory runs the IOC Test
• Running "make ioctests" in EPICS_TOP recursively runs all tests (including this one), this is done as part of the IOC system tests jenkins build and the results are correctly uploaded to jenkins
• It is documented on Move emulator and IOC tests into support module #6556 how to do this exactly for other IOCs (remember to preserve history)
• The wiki is changed to match this new structure
• The ioc generator script is corrected to match this Pulled into IOC generator: issues #4659

we should document that as a developer we should still run the command from support\ioctestframework\master as it is more verbose and you can more easily pass options to the command such as -f or -tm DEVSIM etc.

on the build server or just running for sanity you could use make ioctests

Can you add the ability for the IoCTestFramework run_tests.py and the drivers associated tests to be called via a bat file in the driver directory. As discussed this improves the developer workflow for being able to see a line-by-line output of test results. We are a happy for now that the make ioctests does not give results until finished if this is an alternative option.
