Follow on from #14054

Summary of the issue:

When tests are failing in an unusual way, it may be helpful to be able to review verbose debug logging for interaction with MSAA or UIA.

Description of user facing changes

For developers:
VERBOSE_SYSTEM_TEST_LOGGING can be set (to "true") via Appveyor settings to enable high verbosity NVDA logging.

Description of development approach

When the environment variable VERBOSE_SYSTEM_TEST_LOGGING is set on appveyor, the system tests are started with an extra parameter (verboseDebugLogging='True') which enables the advanced logging categories in NVDA.

Testing strategy:

• Run system tests locally with and without the argument
• Run system tests on Appveyor with and without the argument.
